It's a shame that Michele Bigley ("Spontaneity Can Be So Much Fun," July 5) didn't expand her enjoyment of Lava Hot Springs to take the opportunity to relate a history lesson to her children. The Idaho section of the Oregon Trail runs right through Lava Hot Springs and was noted in several pioneer journals. What an opportunity missed to teach some American history: Bigley mentioned the fun of the hot pools but not the history that surrounds them.
