Be careful with any scenario in which you don't have exclusive rights to hunt a specific piece of property on your terms.
I have seen a LOT of people get burned over the years paying for some kinda "group" hunting situation where in the end all they really appeared to do was pay for all the leased land for some local "guide" to take people on pay hunts.
Then when you showed up on any given day... you got to hunt where they weren't. Which means they hunted where the ducks were. And you got one of the other holes. I saw guys go all season and never get on a really good hunt.
In MS you'd see them stick their "members" on a catfish pond complex while the "guides" took some pay hunters to the timber hole full of ducks.
Unfortunately.....I think this is the angle this outfit runs.
