Hi,
I live in Largo also. I'm new to archery but have lived in Pinellas County most of my life. I'm quickly discovering there isn't much Archery support around here. At least I haven't found much yet, but still looking.
I started out in the house for my son and me. After a half dozen holes in a door (luckily they're only $40 at Home Depot to replace) I moved to the garage.
My son (7) shoots from the garage door to the back wall. I shoot from the end of the driveway to the back wall. Appropriate backstops and targets are setup.
He still shoots in the garage with his Genesis at about 15lbs, but I'm moving up to 50lbs+ now and afraid I don't have enough backstop setup. Plus, I have 'older' neighbors and am self conscious about standing at the end of my driveway in plain view and having the neighbors freak out and call the cops! hahahahahaha!
Bill Jackson's used to have an offsite archery range. Not sure if it's still open. You'd pay at the shop then drive up the street to it. I like their gun range. Agreed, they don't have crap for archery gear though!
This place has a nice indoor range. Haven't shot there though. I've visited the shop to buy stuff but haven't shot there.

This place has an outdoor range with 3D targets. We go there at least every other weekend.

Both places are far, but we really like Britton's because it's outdoor (covered) and it has the 3D targets. The owner is really nice, helpful and easy going. The place gets very busy so we always show up as soon as it opens and stay for 1-1.5hrs depending on how busy it gets or how the boy is feeling. He's usually done after an hour.
