Who can I talk to? Advice needed?

[vinyl-raven.livejournal.com]

I am running a event on Halloween in Union Sq. there is limited parking. I plan on asking Market Basket & Somerville PD for the go ahead to use MB's parking lot.

So, Is the Somerville PD, the people I ask? or Do I go to the Somerville Parking Authority?

I don't know in this case if its in thier (Som PD's) hands or just in MB's and thier tow companies hands.

I am willing to try all my options

Thanks in advance
