Awesome idea.
When I was his age me and a couple friends would ride our bicycles to a shop outside of town that would give us a few every now and then. I remember getting STP stickers every time!!
@Woody'sScamp I have one I'd be happy to send you. I'll send you a PM, just reply to the PM with your address and I'll get it to you, no cost. Like @Coyote Jack , it's nice to have it go to someone who will learn from it.
