Hmmm, Winter in BC on the coast. That's where the Prairie people go to escape -40C winters. Those that can't get south anyway.
I'm from the Prairies and I haven't seen a winter here for 11 years and am hoping for 11 more away. We leave mid Oct and come home mid April. Seen a lot of the southern states and decided Fla was what we liked best.
Head south pick a route and head east, Anything above I10 in winter will be cool to cold. Spring on the east coast will be busy. Go to routes thread on here and ask about routes. Lots from BC go to Fla and all parts west..
