The second mailing may include a letter from your teachers (depending which course you are in) which will include requests for you to bring anything unusual. For example, kids in the archaeolgy course will need boots, light weight, long sleeved shirts and items of that sort. Students in the paper course might be asked to bring dryer lint. At Gov School, you just never know. If you plan on bringing the usual supplies, you are all set unless and until you hear from your specific teachers.
