Then tell the merchants of the Bay Centre to cover the cost of parking for their customers.

This may drive the JBNEA crazy, but why not use Ogden Point for parking here in the off-season? It's a big ol' massive parking lot. And it's only a nice 15-20 minute walk to town, closer to Legislature.
And provide the park and ride type service that they made a big deal about on the vacant car lot.
