I haven't tried OnX yet, but that's what I plan on using for my main tool. I did a trial of GoHunt and liked it, but I've read it's just not reliable on an app platform in the field and is kinda clunky in navigating on mobile.
I do like the GoHunt features for the draw odds, tag research, etc...
I always enjoyed just going to the battery and market street. The aquarium is fun.
Definitely would recommend going to Fort Sumter if you like historical things.
More of a fight as to whether or not ATF has authority to make their little "rules" and create law. This case will affect others like the pistol brace rule, the auto key card case, etc.
