Here are three more sites to add to the information list for traveling. I use these when I decide that it is time for me to proceed back home to Anchorage each year. The first is road conditions in the Yukon Territory. The second is road cameras in British Columbia. The third will assist for road construction in BC.

Be safe. If you are going on I5 in WA toward Canada, there is an RV Park (Bellingham RV Park) just 20 minutes from the border at exit 258.
