When I quit clubbing in my late 20s, I started snake hunting. Let me tell you that the one thing that kept me from driving off of numerous cliffs in the middle of the night in Davis County was loud screaming rock and roll. Joe Forks always used to say that the reason I rarely saw graybands was that the bass was shaking my eyeballs too much. Snake hunting and music go well together, the music often acting as a soundtrack or mood enhancer to what was usually a long monotonous drive.
I remember driving east on 90 between Sanderson and Langtry listening to the Doors' "Riders on the Storm" as I dashed from rain shower to rain shower, parking at 5:30am overlooking Lake Amistad watching a lightning storm over Mexico, the sun dawning to the east and "Dark Side of the Moon" providing an aural backdrop, or dodging 18 wheelers and weekend boaters zipping down 277 on a hot friday night with some Soundgarden to help keep the pace.
I have found that the best band to road hunt by is by far the Austin Lounge Lizards. Their bluegrass/country/rock music is wonderful to behold. Album names such as Creatures from the Black Saloon, Lizard Vision, and Highway Cafe of the Damned gives you a good idea on the type of bizzare songs that are on the albums. With titles such as Golden Triangle, Old Fat and Drunk, Jesus loves me but he can't stand you, and Hillbillies in a Haunted house, you just can't go wrong. I have traveled many Texas miles listening to this group, and I have found that along with a big gulp, a couple ham sandwiches, and a cruise control set at 25mph, the fun just lasts all night long. I would personaly vote the Austin Lounge Lizards as the official music of road herping. Nothing better then finding a nice suboc while listening to "Another stupid Texas Song".
