... for this first time though I think we'll go to the one closer to Austin/Marble Falls:

http://www.hiddenfallsadventurepark.com/fees.html

the gate fees are a little steep (about $50 for two people) compared to places that are further away, but, save on gas for the trip back and forth... since this place is about 15 miles from me.

Anyone wants to join in, we can go any Saturday in July except the 4th. Saturdays are probably a little crowded but the 4th will probably be "saturatus maximus", that's Latin for "too crowded" for Ldub who prolly dunt unnerstan Latin . So I'm open to whichever Sat. the most people that want to come can commit to. REGULATORS! MOUNT UP!!

July 11th,18th or 25th. Y'all tell me...
