Everyone's idea of "the usual stuff" is different. To me, the "usual stuff" is a pretty complete list of gear that let me be self sufficient. When I used to lead Scouts, their parents' idea of the "usual stuff" was a cotton sleeping bag, huge 4-AA flashlight, and 7 changes of cotton clothing.

Could you give us a more complete list of "usual stuff"? Also, what is the trip leader giving you as a list of gear your child should bring?
