Welcome!

I lived in that area once when I was very young, on a ranch out near the Ft. Davis/Marfa area. That's where I first discovered my love of horses.  Apart from that I can't say I liked it much, except the Marfa lights are pretty interesting.

I don't know much about 4-aco I hope you'll share some of your experiences with us. You've definitely come to the right place to find out about extractions, and you're probably in or near peyote country out there too so that's fortunate for you.

Enjoy your stay!
