Please tell me that's a joke... I've driven the Alcan 5 times... they are by far the most epic drives of my life. I've done it in Feb (ferried up to Hanes First time as I wasn't sure about the fuel thing) October twice, April, and March.
The fuel isn't a big thing as it used to be. all service stations I stopped at were pay at the pump so you don't have to have the actual station opened... and I did it in an 87 Toyota Pickup with 35's that had a 13 gallon tank and got MAYBE 10mpg (had my motorcycle in the back) in Feb and had no issues with range.
if you did overestimate the drive, please... for the love of god, drive back. I promise you'll want to at the very least buy me a beer! lol
Hope I didn't come off as too much of a prick... just really hope the propaganda of the "closed gas stations" didn't get you... (like I said, it got me the first time, but I was in the military and PCSing up there, and couldn't ship the rig and was still able to drive the last portion from Hanes in the Yukon to Anchorage, as I only had a week to move from Sacramento to Anchorage)
