I heard it on the radio yesterday while reloading ammo.  It's on the web now:

Idaho 55 at the Rainbow Bridge was closed for about six hours Tuesday after a suspicious object was found underneath the bridge.

An ITD spokesman said investigators were conducting a routine bridge safety inspection around 9:30 a.m. today when they saw an object they could not identify. It was a green bucket with wires poking out.

Idaho State Police and the Boise Bomb Squad were called in to investigate and 17 miles of highway was closed. Investigators determined the bucket was filled with trinkets, photos and toys placed there as part of an online scavenger hunt called geocache. Players use a global positioning system to find the treasure.

Police say the man who stashed the object under the bridge has come forward and charges might be filed against him.

As it was said in a geocaching forum:

Consider. If all it takes to shut down the country is to toss ducted tape tupperware full of rocks with an old radio in it out the side of your window while you are driving down the interstate, then it won't be long before terrorists start causing disruption in a mass scale by doing exactly that. 

There are an almost infinite number of things we can't and shouldn't defend against.  Money is better spend attacking the root of the problem--extremist Muslims.  We must destroy their culture.

About 18:30 on August 19th (Friday night) Barb and I decided to go to the B-23 bomber that crash landed on Loon Lake and slid into the forest in 1943 for our 29th wedding anniversary.  We threw some stuff in the Jeep and drove to Riggins expecting to find a motel in either Whitebird or Riggins.  There were none.  The fire fighters had taken what the tourist hadn't.  We ended up finding an open spot in a campground just off the Salmon river about 12:30 AM on Saturday morning and slept in the Jeep.  After waking at about 6:30 we drove about 50 miles, mostly on one-lane roads, to Chinook campground.  We hiked ten miles round trip from Chinook Campground to the crash site and back to replace a missing geocache (B-23).  Barb had not been there before and was very impressed with the site.  The pictures are here.

On the way out we figured we should go through McCall to improve our chances of finding a motel.  We arrived back at the Jeep about 18:00 tired and sore.  From the Chinook Campground it took us only an hour to reach McCall. Again, the motels were all full except for a luxury suite for $225/night.  We drove to New Meadows.  Again, all full.  We called several motels in Grangeville.  Again, all full.  We drove north, dirty, tired, and getting hungry.  At Pinehurst we found a motel with a Vacancy sign.  We rang the bell and waited, and waited.  Finally a man appeared to tell us his "No" sign was broken.  We drove to Riggins and found a motel with two rooms available.  We were thrilled!  We showered and went to dinner.  It was about 20:40 when we walked into the restaurant.  Except for the cook and the waitress we had the place entirely to ourselves.  Riggins appears to close up early on Saturday nights.  It was great food and we went to bed tired and very happy.  It was a great day in the woods and one of our best anniversaries yet.

Barb and I went to Moscow Mountain for some geocaching this morning.  It was a most successful and rewarding trip.  First we replaced the Moscow Mountain High ammo can with the bullet hole in it:

Then we found Moscow Mountain Higher which we were not able to find on our last trip out on June 4th:

More pictures can be found here.

One of the first geocaches in the Moscow (Idaho) area was this one which I placed March 11, 2001.  A fire on September 8, 2001 destroyed it.  I replaced it on April 4, 2002.  Then the location went under new managment and no trespassing signs were put up (unrelated to geocaching).  Barb and I moved it a few months ago but I just now got around to getting good coordinates, a picture, and reactivating it.  It used to be called "Stumpy" but I renamed it "Rocky" in the new location.  Here are current pictures of the cache:
