Amherst Parking

In Amherst, MA you pay for a parking sticker that theoretically allows you to park in the street. Interestingly, you cannot park on the street between December and May (they will ticket and tow your car). So what becomes of the people who do not have driveways/on-site parking? We would like your comments as we will soon submit an official letter to the town requesting that one area be reserved for those folks who live in town, pay the fee for a sticker, and do not have on-site parking.
