Good luck on your horse search! Remember to keep an open mind! I hated riding big horses, and didn't want anything over 16hh (huge in my mind) I ended up with a 16.3hh beast who is NOT still growing (in denial)
And, a big bodied horse might carry you better then you might think. My long bodied 5'11 dad fits my 15hh Qh/Paint better than his 16.2 TB.
Haha! I'm glad you like yourself some tall horses, you can keep them! :) I'm all of 5'3" with short legs and perfectly happy to stick with those that are about 15 hands myself. I'd probably need a stepladder to get on something 18h tall!
I hope your trip goes well and you find what you're looking for. Make sure to share pictures with us if you do (or even if you don't).
You might also look a QH if they fit the bill in all other ways. There are horses out there that are in the AQHA registry that are 7/8 TB, and they can get really tall. 17H for QH in English is almost the norm, and one horse that I'm looking at is 16.2 as a two year old with a brother who is 18.2. Best of luck, though, and let us know what you find!
Cool, that's near me.... we found a horse we wanted to buy just recently but we figured we had time since its slower in the summer and she got snatched up. Lots of great barns and trainers around here. I would say come see my horse but I think I am keeping her (in love) and besides she doesn't fit the bill in many many ways LOL
You will have fun, be prepared is darn hot right now and humid.
