When I do not have parking, there are a couple of places you can park. If you look on the parking map they're on Brightseat road, just to the left of the big "495" highway sign on the middle of the map. Also a good way to exit after the game.
Also, if you're looking for a reasonably priced pair of tickets to this game, I have a pair in 451, Row 22 for $75 each, and I'll also include a big color glossy map of the parking areas (same view as the link from the web site)that the Skins send with parking season passes.
