I have one of those portable camping gas stoves (like Coleman 2-Burner Propane Stove at REI.com). It uses small gas canisters (like the one shown here: Coleman Deluxe PerfectFlow Propane Lantern at REI.com). I also have a gas grill that uses standard big gas tanks (shown for example here http://toolmonger.com/wp-content/uploads/2007/08/TM_gg.jpg). Can I find some sort of adapter that would allow me to connect the large gas tank to my portable stove? Thanks!
