Just moved to "Winchesta" from the west coast. Before I left I kegged my last brew and put it on gas in the moving truck and drove 3K miles - called it the cost-to-coast IPA. When I pulled into Boston and plugged in the kegerator - t'was flat - no gas (wasn't much in there when we left, guess it got absorbed). Every where I called was swapping but I didn't want to give up my shiny tank I purchased new. Finally found Igo's Welding in Watertown that filled my 5# tank for $25 - a bit pricey given I paid $15 in L.A. but I don't mind paying a bit more to keep my tank.
