I forgot to mention, there are other areas besides Juno Rd.
Juno has been both good and horrible to me some years. First alterna I collected was on Juno in 93. Langtry is also about the same. Most seem to like 277 the best. Which like any other crowded road can become a carnival of lights, cars and wishing aliens would beam you to a quiet place all by yourself.
Juno is good, just walk the curves, be slow... The land owners may pull over or stop to talk to you. I would not panic, be polite, let them know under no circumstances are you going to trespass, and they will hopefuly leave you alone. Most just don't want you trespassing on there property. It sounds like a load of mess, but when you get pulled over or questioned you are a "representative" of the herp community. I find that politeness goes a long way. I have only lost my temper a couple of times out west. Most of the time it is just other collectors cutting you off on roads, or u-turning in front of you.
I hope you do well. You don't have to give spots or anything but let us know what you "saw". Also I would not post anything until you return from your trip. Last year I posted while out in "west texas" and the wardens were out in our area the next night. We were not doing anything illegal but it is still a bit of a hassle.
Again good luck,
