Change of plans

So we found out at 11pm that the highway we were going to take tomorrow is washed out. How you ask me when it has been sunny? I have no idea other than I have heard that the US side of the highway isn't well maintained. So since there is only one alternative route, as the highway won't be fixed for days and the forecast is rain, we have to go back to Whitehorse the way we came and then back up the other side of the Yukon. Then we hope to go to Kluane park and camp a day earlier than planned. If they don't have any campsites well then if I have learned anything in the Yukon you can just put up a tent at the side of the road!
