I'm gonna be up in Vancouver for a few days in May! Also a few places in Washington.
There's a lot of places to enjoy all around there. Try to get time to take the ferry to San Juan Island or over to Vancouver Island and Victoria. If you're looking for boonies, Olympic peninsula and North Cascades has 'em.
I'll be staying at some spots around the Olympic peninsula for some hiking. Might be in Victoria as well but not too sure yet.
