More convenient is Astoria Hot Springs, also near Jackson. It also has a nice patio overlooking the pools for parents whose idea of a good time is a long, slow soak in the sun. At the foot of bluffs that box the Snake River Canyon, Heise has a soaking pool and two play pools, along with camping and picnicking. Best of all is the big waterslide. It has three pools that range in temperature from about 90 degrees to more than 106.
E is for elk bugles.
Buy one at a sporting goods store almost anyplace in Yellowstone country and drive your parents crazy while you learn to produce the whistling call of a real elk bugling. Cow calls are cheaper and easier to use than the bull elk bugles, by the way. Don't bugle in the parks, though, because it's illegal. String your fish on a stick, Tom Sawyer- style, pick a piece of grass to hold in your mouth like a giant toothpick, then take your fish home and ask Ma to cook them up for dinner. Teton Valley, Idaho, and Jackson, Wyoming, both have kids-only fishing spots.
