If you do not already have hiking books for Devil Pup camp, now would be a good time to get them and get them broken in. Here is a photo of a boot that is a good camp boot – you will need protection for ankles with all the activities at camp. Watch for sales at Big 5 - don't buy heavy boots that won't "breathe" - they will get a lot of wear at camp. Wear them every day for two or three hours to break them in.
As for the rest of your packing, please see this list on the Devil Pup website:
