MMario,

I see you don't know much about road kill. It is the season that is most important in harvesting road kill. It's true that in the summer when the pavement is hot, only a short cooking period is required. Winter is another story altogether. With cold pavement (or gravel, dirt, etc.) quite a lot of time is needed.

You're not one of those city slickers that just picks it up fresh, takes it home and nukes it are you?
