Disclaimer: What I say below by no means should be understand as me taking a crack at the kids on this thread. I'm sure they are all great kids and I'm a big fan of giving calls to them, but.......
Back a few years ago on another forum there was a "kid" who was asking around for calls, decoys and camo to help him get started hunting. The amount of things the people over there sent him were amazing. All kinds of duck and goose decoys, some VERY nice calls and some great camo items they or their kids had outgrown. About 2 months later some of the guys who had donated whatever started noticing them up for sale on eBay. The kid had suckered them and was making money.
Like I said above... I don't think any of the kids on here would do something like that, but keep your eyes open. I no longer send calls to kids on the internet unless I know someone who can vouch for them. Now I prefer to give them out on the boat ramp with their fathers present. Both the kids and their father appreciate it.
