I’m late to the party, but I will chime in!
I lived in New Braunfels for multiple years as a horse girl that rode hunter jumpers.
I worked all over the hill country and loved traveling from town to town.
My personal horse was boarded close to home for a while at a private spot before I put him in full care with my trainer out in Boerne.
The Hill Country is beautiful. Its unique in that there is scrub and rock, but there are also places and pieces with lush grass depending where you go. The Hill Country is quite vast. New Braunfels and a piece of Austin barely lie within the boarders of the Hill Country. San Antonio is not Hill Country, IMO. However, I’ve heard people tell me NB isn’t Hill Country. You can go as far south as Concan and as far north as Llano & Marble Falls. All this to say - your geography, snake experience, and people experience will change.
The “larger cities” in the Hill Country are quite diverse IME. Yes - you have die hards on both sides of the political spectrum. I think you’ll get that anywhere in most Southern States. However, to echo someone earlier in the post, the biggest Political encounter you will get is the Texas Pride/Die Hard Texans.
Weather, again in NB, was quite mild in the winter. The Summers are HOT and LONG. It snowed a couple times in my time in NB, and that was more on the rare side. You’d get some ice here and there. Its not a joke when we say we were in shorts on day in December and then full winter gear the next. Tornados aren’t super common. We had a few hit San Marcos, San Antonio, and Seguin when I was there, but that was as close as they’d come and the were ~F1-F2, so pretty much major wind storms with a lil rotation. Not the F4s & F5s you can get up North TX.
The HJ scene is there but its definitely small. If you want to show A/AA or even most schooling shows, you will have to travel to Houston for 90% of them. Tyler for the other 10%, maybe, if your trainer doesn’t hate Tyler. Most trainers get the hell OUT of Texas in the Summer, going to CO, KY, MI, IL, and NC to escape the heat. There are schooling shows in San Antonio, Dripping Springs, and Houston as well. There are some hidden gem trainers in the Hill Country, don’t let people tell you its a hunter jumper waste land.
As for snakes, just teach your kids not to poke under rocks or brush piles. You’ll probably never see them. Honestly, I only ever saw them when my dad sent me photos or the one little coral snake I pulled out of his pool drain. He’s had a couple dogs bitten, and he’s seen quite a few on the ranch, but it’s not something they are overly weary of. When he’s setting up feeders & deer blinds before season he will wear his snake boots and be a little more cautious. Scorpions are everywhere in TX. You can treat for them and usually it keeps them at bay. My cousin did get stung at my dads once while sitting in the hot tub, but that was definitely a one off occurrence. Treated it like a wasp sting.
To wrap it all up - I love the Hill Country. I love the lush rolling green (when there is no drought) hills of North Texas more and it fits my lifestyle better now, but I don’t regret my time in Hill Country at all and we go back OFTEN for vacations and get always. We have a resort in Hunt that we love, SO & his buddies go on boys trips to Concan to fish and tube, and we try to get away once a year to Fredericksburg. We have family all over NB, so we get the luxury of going to visit them whenever. The Hill Country is a unique place with great history and food and full of good people.
I’d recommend you come visit in the summer. Pick the towns you’re thinking of and just do a trip to experience them all at “peak season”. Experience the Texas heat, the people, and the driving. You will know if its the place for you or not!
Before I settled on N TX, I very heavily considered Franklin TN & Lexington KY as moves, so those might be two areas you can look into or surrounding areas! Happy Hunting. I know its stressful but there is a perfect place for you guys.
