I am meeting a friend from college on Saturday, May 26 for some paintball in Bowie, Md.
Paintball is hellla fun and quite memorable. We go to Outdoor Adventures where they have lots of different courses on 80 acres of property (all outside) complete with forts, trenches and dugouts. It might be a fun alternative (or addition) to your Saturday run. I'll probably run later in the day.
You do not need to own your own gun to do well and have a good time...obviously having your own (such my Blastmaster 673x Data 56) can be helpful.
Let me know if you are interested. I can drive anyone from Md/Beltway to Bowie.
