Update on your planned trip through idaho. We just finished checking out a park at exit 216 I 84 dirty and full of mostly full time residents. The park at heyburn is nice. Its got river access and a walking trail but it is off the freeway about4miles. My personnel preference is the three island state park at Glenn's Ferry, ID. Plenty of side spaces, lots of trees, next door to a winery and golf course. It to is about4 miles off the freeway but no road noise just the occasional train since it is an old train town. Not any good places to eat is the only real negative. Bliss just eat of there or mountain home, just west would take care of that problem. Let me know if I can be of any help. PS swing into twin falls and watch the base jumpers and see where evil kneivel tried to jump the canyon at the173 exit at the perrine bridge.
