Advice for Pothole Claim in Massachusetts?

[keithbedard at verizon.net]

Greetings Audiholics,

A couple of weeks ago I finally got around to putting on my summer wheels 
which are Porsche "Cup" alloys machined to a 45mm offset. They are about two 
years old, and I clean them every weekend. They look beautiful, which is 
probably the reason why after only two days of them on the car, I managed to 
nail the biggest pothole this side of the Mississippi, which is in the Fort 
Devens area in central Massachusetts on an on-ramp to Route 2 West. This was 
the mothership, and as I was hitting it, I thought for sure I would not only 
bend one of my sacred rims, but also blow the nice new rubber, too. Rubber 
survived, rim bent and doesn't feel to good (shakey, vibrating) when driving. 

I am furious that such a large pothole was not maintained. I would like to 
be compensated by someone (city, state?), but fear that it is a wild goose 
chase, as I don't know who is liable.

Anyone have any advice or relevant info they could share?

Much obliged,
