I need Halloween costume ideas for my son. He will be 2. We live in GA and it will still be warm so my Elmo?

idea is not going to work. The big, furry suit will end up off in the street. He was a fisherman last year. I've thought about making him a hunter OR his dad IS a big hunter, so I thought about dressing dad in his hunting camo and dressing my son as a deer. HELP?
