If you have to do Texas traveling on foot most of the year you’ll might want to do it like the border jumpers do –go at sunset and mostly at night hence a headlamp or small=powered flashlight and that extra canteen of water would make life worth living, just don’t wear flip flops, mocs, crocs, or narrow sh*tkickers. But if that’s what ya got better than meeting nature “nerkid” and afraid. How much water are you carrying while you drive our Lone Star state? I carry a six-pack of water always covered from sunlight, which will impact the plastic bottles. I try to replace them as I drink them.
