Stay safe! I've been through parking lot hurricane evacuations too, slow traffic, no place to gas up or get off the interstate to use a restroom. During the hurricane Rita evacuation in 2005 it took us 8 hr. to drive to my parents' house which is farther inland, a drive that normally takes 1.5 hr. There were people who died in the mass evacuation ahead of the storm, many from heat exhaustion after running out of fuel, water, gas, etc. Be careful evacuating!
