That's cool. I"m kind of a crusader for small people getting into hunting. You'll grow of course, but I'm 17 and smaller than you, less than 4 foot 8 and 73 pounds.* I pull a 30 pound bow and got my first deer the day after Christmas.

Sodon't let yoursize stop you.Go out there and hunt. Just make sure to focus on shot placement.

*(I actually weigh a bit more than 73 pounds at the moment, but it's only temprorary.)
