Hi Bob, I recently made the trek from Houston, Tx. to Anchorage Alaska on my new 03 Wing. The total trip was 11,299 miles and worth every mile. Most beautiful country I've seen to date!!! The Wing was the perfect bike for the trip till we got to Whitehorse in the Yukon located on the AlCan Highway. After Whitehorse the road conditions went from fair to very bad. Alaska suffered an earthquake in Feb. of this year and some of the roads split open. The construction crews had their hands full packing the damage with dirt, gravel and sand. If you are going solo I suggest you take the GS. I almost lost control several times in the muddy construction areas and in the loose gravel. Some riders, once they entered Alaska, refused to return on the AlCan due to its dangerous road surface and shipped their bikes back. I rode back from Anchorage, returning through the gravel once again,,,and the trip from Anachorage to Tok, to the Canadian line to Haines Junction was very dangerous. Maintaining control took a concentrated effort...plus the discourteous truckers passing the other way through the loose gravel pitted my windshield and front fairing...I just ducked behind the shield and kinda wished I had my pistol. Again, the GS would have been the wise choice for the last thousand miles to and from. The country and the wildlife are so beautiful that words don't do them justice...I fought the tears back when I saw some of the sites. It's the way God intended the land to be before we messed it up! Your GS, if like my recent R series Boxer, requires the high octane stuff, There were times on the AlCan that 86 was the only fuel available and I was happy to get that. The Beemer may be OK with 86/87 at those altitudes...may want to check that out before taking the GS. ...the Wing did fine on this fuel. Suggestion, use your Mastercard/Visa while traveling through Canada...they make the conversion for you and it saved me a lot of confusion with the exchange rate...expecially when purchasing fuel. As far as planning is concerned...my wife and I just jumped on the bike and took off...no planning---had a BLAST!!! Best to ya...if I can be of any help please feel free to E-mail me. Rick
