Getting meds while on the road?? [View all]

I'm in California.
My wife and I are going on a 5 month RV trip to Alaska.
Don't want to cross the international borders with it on us especially coming back in to the USA.

Any suggestions on where in British Columbia and also Alaska to get FECO, edibles, and/or flowers?

We really need our cannabis meds for sleep, etc..and it's a shame I can't bring my homegrown flowers and also edibles I've made with us. I have a lot.
