Please give your opinion on my parking options. :)

Hi. I live in Maine and fortunately I have nice inside storage from November till May but till November rolls around again I am outside. Here are my choices:
1. Park on the asphalt as pictured. Problems include it is a high traffic area and the rain gutters empty out right near my Dart. Good points-It is shielded from most of the wind.
2. Park in the dirt. If I go this route I have bought 6 mil 10X25 plastic sheeting (vapor barrier) that I would staple down and then put sheets of plywood on top of this. Problems-not shielded from wind and more birds. :)

Any opinions are greatly appreciated. Thanks!
