I'm 26 and have many friends my age that hunt (maybe too many) As far as being respected, I would say that the only thing my elder hunters hold against us is that we are taking away their hunting land. The ol timers I hunt with all talk about the good ol days when they "could hunt anywhere and there were birds everywhere, even in that subdivision over yonder"
Most of them have adjusted to they hunting sytles and have excelled at it.
