B.R.
Hi C.,
My church has a gymnasium with a kitchen and shower facilities that might work for your group. It's located in the north/central part of Austin, very close to I-35, so it should be convenient to all the locations you'll be going to. It isn't usually very busy in the summer, so I think it might be a great fit. It also has multi-levels, and individual classrooms, so you can separate the boys and girls pretty easily. It is Red River Church, at 4425 Red River Street, (on the corner of 45th), and the phone number is ###-###-####. The office email is ____@____.com tell them B. referred you, and they'll know who you are.
You can also visit the website--www.redriverchurch.org, to see a map for location, and some photos of the facility. It tells a bit about who we are, too. Blessings on your endeavor! Your organization sounds fantastic!
