I hired Texas Climbing Adventures to guide our group of 15 on a climb at Reimer's Ranch. This was my first time hiring his company--I've used others. John Deas gave us a great price from the beginning and his previous reviews were fantastic. Our group had people of varying abilities and ages. The day of the climb, We had 3 awesome guides from TCA. (John was with another group at E-Rock). We basically climbed in 3 different locations all day. The guides were very good in terms of safety (#1 concern always!!), training us and encouraging us to push ourselves. The only thing I would say is that if you have a big group, make sure you know what size shoes everyone needs--we were a little short on large sizes and some of the guys had to share (takes more time...) I would definitely use them again!!!
