declining hunters is problem just about everywhere,
i dont think the solution is recruiting out of state hunters,
financial benefit to your state yes, but not the solution to declining hunters,
but thats just states fighting over dwindling hunters $$$.
only solution to that is recruiting new hunters, young and old,
as more people move around cities less opportunities to hunt,
to recruit the young, parents have to expose their kids to the outdoors, and hopefully their kids will recruit friends,
for older hunters, have to educate them on benefits of hunting,
great way to start is to recommend anyone who loves the outdoors to get their hunters ed cert,they dont have to actually hunt, but they will learn alot, and maybe a small percantage who take the course will decide you know what, think i'll try hunting,
that hiker/biker/camper who spends alot of time in the field but doesnt hunt, may decide to try it.
also educate them on the food source available from hunting,

new hunter may be overwhelmed with idea of harvesting a deer,
but they may be interested in going out and pursuing some small game for some meals,

best thing you can do to promote hunting is educate others on the benefits of hunters,
how its the best practice for the conservation of the animals we have,
