I'm planning to take some nice Mtn rides this spring and worry about my fuel supply. I have a luggage rack and a nice tail pack that could hold a 1 gallon plastic gas container. I might be able to fit 2 of them in it. I'm trying to think of a reason that this would be a bad idea. I realize it's not ideal solution but the thought of adding 60 miles to my range is pretty tempting. Has anybody else done this ? Let me know what you think.
