Don't know about the Escalade but, I've seen that county mounty in that F-150 about 3 or 4 times on sisters runs - he has a couple of favorite spots as you come down a hill where you described and there's one around Hwy. 187 where the zig zag is that goes up to Lost Maples on 337 on the side towards Medina. Also, have seen radar on 337 between Leakey and Camp Wood. Also have seen radar between Medina and Bandera. Also have seen radar between Bandera and Hwy 46. Agggghh! Fortunately, my Escort continues to pay for itself! Sorry you got popped. That old white guy was probably the judge of the kangaroo court you'd have to go to if ya intended to fight it in court!
