The multiple reviews regarding poor parking are spot-on. I always try to avoid coming here when there's something going on at the stadium, because I know people are going to flood the parking lots... And either I'll end up parking on the other end of the lot or across the street - after searching for fifteen minutes - or I'll have to pay a ridiculous $15 for a spot - or both.
One brilliant reviewer snidely remarked that if you don't like the parking situation, you simply shouldn't come here and definitely shouldn't have the NERVE to leave a negative review over it. I'm not sure what they think the point of Yelp is... The purpose of leaving a review is to inform other potential customers of any issues you had, so they can work to avoid them, and it also serves as a means of bringing larger issues (such as parking) to the attention of the property owners so that they can actually be FIXED.
Yes, actively avoiding the area during large events is a great way to avoid the issue. But it shouldn't be necessary. The stadium has its own parking lot that was built specifically to accommodate the capacity of the stadium itself - parking in neighboring lots therefore shouldn't be affected by it, and certainly not to this extent. Last time I got caught in this type of situation, all the high-clearance vehicles eventually resorted to mounting the curbs and parking in the grass areas. That should be a clear indication that something's wrong with either the parking lot size, or (more likely) the parking system in general.
My only current solution to this problem, without completely avoiding the area:
Take the motorcycle. Two wheels are better than four, anyway.
