Actually not hard to do in the ATL. There's at least one IDPA or USPSA indoor match Monday through Thursday night. And there's either an IDPA or USPSA or ICORE outdoor match occurring every weekend. Sometimes more than one. So by going out 2 nights a week that's 104 matches, then add in say one match every weekend for another 52, it would be easy to top 150 all within an hour drive.
We're very fortunate, with ~10 indoor ranges holding matches each week, some hold 2 different ones each week. Then within an hour drive there's 5 major outdoor ranges; River Bend (Dawsonville), Cherokee(Gainesville), South River(Conyers), Griffin(Griffin) and East Alabama. Make it 2 hours and you can add CMP and Ft Benning. There may even be more, but those are just off the top of my head.
