Welcome, Melinda !!! I sure hope you lurked for awhile so you know what you have gotten yourself into joining this bunch
If you want laughter, plenty of humor , and caring friends, you are sure in the right place. Alaska, is a Great place, I loved it and would love to go back for 5 or 6 months, but if 3 weeks is all you have, go for it. Then you'll know you must go back for the rest of it. If you drive your r.v. up, you won't have much time there, the trip up through Canada is wonderful too.
So glad you've joined us, and hope you will add your imput wherever it strikes you.
Safe and Happy Travels,
CArol
