Sporting an NRA sticker in Massachusetts might _not_ be such a good idea.

  An even worse idea is driving your Westy with propane on board
through the Ted Williams, Tip O'Neil, Sumner, and Callahan Tunnels.
(try driving in and around the city of Boston on a daily basis without
doing any of the above)

   I am not sure what the regs are for the Tobin (formerly Mystic River) Bridge.
