If you travel alone, don't go dressed to get attention. Dress to blend in so you don't get a lot of attention, because some of it can be negative attention. You're alone, and you're probably far from home since you are traveling. Be safe and just blend in.
Bring an, "Everything, but the kitchen" bag. I carry an extra set of clothing, shampoo, Rolaids, band-aids, wipes, etc. If you're traveling, you never know when your car breaks down, or you need any of this stuff. Anything I can think I might need, I have it all in one bag.
Get a zipped file holder. Print out a lot of the authorizations you use a lot such as, if you do a lot of Shell stations Exxon's, and Phillip 66's, keep at least 10 of the authorizations so if you are out of town and see you can do one of these jobs, take the job because you already have the authorizations with you.
