Wow, Oddjob. I can see I really need to pick your brain! I have only been here 6 years, 5 of which I worked so much, I never saw anything but work and my home. Now I am really getting to know SA!
You know where Helotes is I take it; right on the corner of Bandera and Leslie is the old fair grounds for the Corn Festival. Looking at the maps it shows starbucks on that corner now, but behind it is still a chunk of land and according to google maps it is called Helotes Festival Association, that was all part of it.
You would certainly want to hunt that, not so much near the neighbourhood. but right off the main road where the old quarter and vending games where, dance floor and arena.
another spot down the road called Floor Country store, they used to own a small piece of land on the other side of Old Bandera Rd. Great place too.
Head back the other way down towards 281 and 1604 there is a place on the inside of the loop called Mud Creek Park, really good spot for arrow heads but also MDing as well. Used to me all cattle lands by the same family that owned Bandera road back when all that land from 410 up to Helotes was all one ranch.
Last place and then I will stop. On the outside of the loop off of Kyle Seale on the left side if your if your pulling into the parkway. Used to be an old Ice House, but a real ice house, building feel back in the 70s and is gone. But all that bush land was really good hunting for native artifacts, MDing and of course more Peyote than you could carry. That area was all owned by the same south african family my family migrated to north america with, the Gillespi family. They where killing it with that Ice House, was the only one around for a long ways, and they had a general store and beer joint way back when you would run your cattle down to mud creek for weigh in at that cattle station.
which by the way some of that cattle station remains still, just a small part next to the recharge zone, cant miss the foundation at all.
But if you need any other spots to go just reach out let know what area or side of town. All that was ranch land back in the day, my family migrated over to North America in the early 1800s with 8 other families, only 3 of the families we still remain in ranching, the rest sold out to commercial land.
