Dazric,
Having just returned home, to Boise. We spent the Weekend in greater Hagerman Valley. So a little history opportunity, and a Geology opportunity, and a Fun Game for the whole family. The Snake River @Ontario is boring, however by to time you get to Gleens Ferry, (has an Oregon Trail Museum, & Camping), at 3 Island Crossing State Park. As you proceed East toward Bliss, You cross the Snake River twice, at the 1st you Could Exit the Free-way, take the trip North along the River to Kings Hill, a town that was "Abandoned" when I-84 was put in. You then return to Highway at the 2nd Highway crossing. Pay attention to the "Scard Lands twin the Road and River" Just to the South side is a boulder debris field of Stones "Left by the Bonneville Flood"... Instead of going to Twin Falls, Exit at the 2nd Bliss Exit, and travel down Hwy 30, down into the Hagerman Valley. As you cross the "Malad River" [Which is Idaho shortest River], you will agian see Boulder debris fields on both sides of the road. SLOW down going into Hagerman. It's a great litte community. If it's lunch time, the Snake River Grill has great food. From Hagerman, headed East you drop into the 1000's Springs scent route, there are at least 4 Public Hot-Springs. We prefer Miracle. There are two Fish Hatcheries. The National Hatchery has a nice display on "Steelhead", a Visitor display pool of White Sturgeon and Rainbow Trout. There is another Boulder debris field at the State Hatchery going to the Bridge. The trip from Miracle to beyond Filer is just down-right boring. BUT so is the route into Twin Falls and doubling back to get ya South on 93. If you have time in Boise, Let me know, I can escourt you guys to a great "River Display" behind the Game and Fish Center. GREAT display of Riparian habitat.
The "Game" to keeps the kids focused outside the vehicle - is to play the License Plate game. Mom plays ref., documenter, A high-lighter for each Kid. They see a State "Not Called" they say "Wyoming", "New Mexico" - keep track over and back, award the winner with some-sort of atta-boy, girl, etc.
