stay the hell out of delray shooting center. The store is a dream, but the staff are 99% pricks. The range is very very strict and overpriced, especially if you're going with more than one person. Markham is fun but a decent drive and fairly strict. No suppressors or machine guns allowed there. For a bit more drive, Okeechobee is the best option for shooting somewhat close by. they allow pretty much anything and the staff is good to deal with. The store is a bit under stocked, but still a great facility.
If you want indoor and close, go do Gunworld of south florida in deerfield beach. Only about 20 minutes from linton blvd and 95, they allow steel cased ammo, suppressors, short barreled rifles, machine guns... basically anything you want to shoot. The ventilation system is very good there also.
If you want to spend some money for a neat experience, drive down to nexus in ft lauderdale. look up their website
