hi yall, broke college kid driving in from lousiana to see a band in a few days. any suggestions for a safe place i can park and sleep in my car for a few hours after the show?

usual do alot of singing and moshing at shows so idk if id feel safe or up for the 4 hour drive home that late at night if im completely exhausted. I see lots of truck stops off of i-10 back towards lousiana and a state rest stop a little farther out of town but idk anything about the area and dont wanna end up in a sketchy place without knowing. any suggestions help thanks!!
