The Retreat is at 20155 San Marcos Hwy 80.
As you head north on I-35, exit 205 which is Hwy 80, Bobcat Stadium exit.
Turn right, go past Wal-Mart, over the river, over the new overpass, past the Pecan RV Park.
Shortly after that intersection slow down. It's on the right hand side, a few houses, small businesses,
a church & then this 1 story, flat roofed, white building.
