The metroplex and Dallas is a huge area. Unless you want to drive 1-2 hrs. to get to the barn, your options will depend quite a bit on where you actually live, and/or work. The barns listed are all good. Flower Mound/Argyle is just north of DFW airport (so between Dallas & Ft. Worth), Rosehill is north of Plano, Buckbranch is south of Dallas. Additionally, there are some options in the Aubrey/Pilot Point area (north of Frisco) or over on the Ft. Worth side of the metroplex, such as Willow Draw, Curragh and PF Flyers.
If you have a trailer, there are more options because you could haul-in to people like Mike Huber/Heather Morris, Ellen Doughty, Kadi Eykamp or Stuart Black.
Southern Cross, where Ellen is, is east of Dallas in Terrell and I believe their board is $600 and it’s a nice facility.
There are a lot of eventers in this area with quite a few schooling show options as well as two H/J local circuits and an active dressage group. You might check out the North Texas Eventing Assoc., Dallas Dressage Club, Ft. Worth Dressage, North Texas HJ Assoc. and Dallas Scholarship Circuit (that name may not be 100% right, but if you google Dallas Scholarship Hunter Jumper, I’m sure it will pop up).
Once you have an idea of what part of DFW you’d be in, we can help point you to some barns in that specific area. Not sure where you live know, but we drive…A LOT in Texas. It’s a BIG place! LOL
