That's wonderful, Steven. You're very lucky, my drive to my support group is 70 miles (one way).
But, please, a note of caution. Coming out to your parents may one of the most important things you ever do so don't rush it for the sake of getting to the next meeting. They'll have more meetings but your parents are the only set you'll ever have. A month may actually be too short a time to prepare them and tell them how you feel.
Of course, I'm not in your shoes and can't know all the details so only take this advice if you think it's a good idea. Maybe a month is enough, maybe not. Only you can decide.
Whichever meeting you get to though, March, June or December, Good luck and have fun!
