Is it really too far to walk to the bathroom at a rest area?

Just a point mentioned several posts ago. Of course it is a trucker(s) doing it. There are no 4 wheelers in the truck parking. Does auto parking area smell like pee? Never ran into that in an auto parking but NUMEROUS times in truck parking. Down south with the heat and humidity of the summer, it stinks. If I get out to kick the tire or walk around to check the hookup, I think about my shoes on that nasty, biohazard asphalt and sometimes hesitate to even wear them back inside. What do you guys do in this situation?
