Had a wall of text ready to go and my connection dropped when I sent it, lol.
I use a cheap barrel grill a friend gave me - his mom was apparently tired of seeing it on her deck.

If I eventually learn to weld an insulated double walled reverse flow is on the list. Something a single chimney of charcoal can run for 15-20hrs... Neighbor has a machine shop, lol.
Venison is really easy to oversmoke. I did a 200lb doe's neck for pulled venison and only the smoke lovers would touch it.
Half frozen backstrap steaks thawed while smoking 20-30 minutes, then seared leaves you with something like super lean rare brisket. Awesome stuff.
Wild pigs don't have as much fat as their farm cousins but I'd love to try. They just need to go ahead and make it to Maryland.

Have family in Tennessee that had the local golf courses hire shooters, so they're making progress.
Best place to start is chicken. I can usually get thighs and legs for under $1/lb. Won't hurt your feelings if you screw those up. Pulled pork takes a ton of time, even at higher temps (and it's not as good)... When you're ready, do a chuck roast. They're nice and even thickness, smaller, and cook faster.
