Bring your kayak or your raft to Idaho. Folks who like to fish will get more than their fill at Silver Creek, south of Sun Valley, the Henrys Fork in eastern Idaho, and countless high mountain lakes in central Idaho. Bring your fly-fishing pole, if you're so inclined. About two hours north of Boise, hundreds of miles of singletrack criss-cross the Payette National Forest near the gorgeous alpine vacation town of McCall. Don't forget your bug juice in this area.
Clothing is optional at night.
If you're a Lewis and Clark history buff, Idaho is the place to ride. Near Lolo Pass in northcentral Idaho, you can retrace the 75-mile overland route followed by Lewis and Clark's Corps of Discovery on the north ridgetops of the Lochsa River canyon. Wild game was so scarce they were forced to kill and eat their horses to survive. Be sure to check out this area before 2004, when the tourists will flock to Idaho in droves for the 200th year anniversary of the Corps of Discovery's crossing of America and the West. The book features 80 rides in all, including 55 singletrack loops.
