its for winter, co2 can actually freeze (michigan=satan's icy crotch forest), but i don't know if there's equipment for those types of tanks that would suit me, or if i could just find some big ass tank and have some paintball store fill it. meh, im happy with me little white half pinter until i actually get up the gunction to do anything. cant do nitrous too often either, itll make you go insane. in the end it doesnt matter, ill always have and cherish my first loves: maraschino cherries and marijuana.
