The one I love is, no border check entering the US at Hyder but there is a Canadian one to re enter Canada. And yes, they do ask some seemingly daft questions & repeat questions sometimes. Easiest to simply answer them & be on your way.
At Dawson City right now. We were going to stay at this CG for another night but it is very expensive, the WIFI is unreliable & only available for 2 hours before there are extra charges. So much for advertised "FREE" WIFI. Postage stamp sized sites too. Guess we have been spoiled by the $12 lovely Yukon Gov CG that we have been using in the past 2 weeks.
Oh well, across the Yukon we go today to enjoy another for a couple of nights.
