Hey Neighbor. I'm a Southsider, too. Crest Manor area.
I used to belong to St. Joe County but they got into a price creep the last couple of years. Joined Howard Township in Niles by Baron Lake. Quick trip up the bypass. Trap Wednesday nights. Rifle out to 200, pistol. Not too spendy.
ETA: Big Tanker mentioned the St. Joe county club, too. OIt's nice and I usually had it to myself most of the time. Rifle to 100. Pistol range is nice, too. They do trap on Sundays.
I liked the place I just thought $90 was more than I wanted to spend
