Yes, I've been to San Francisco several times (a relatively short trip by plane for us living in the beautiful Pacific NW) as I had/have family studying/working in the city and its surrounding area. It's a beautiful city and lots to explore - Alcatraz ( the famous island prison from which no one ever escape, which you can get tours of, after getting there by a nice boat trip), the well-known Golden Gate Bridge, Ghirardelli Square (make sure to go to the famous chocolate shop! http://www.ghirardellisq.com/
, Fisherman's Wharf (Pier 39)(http://www.fishermanswharf.org/
. On my most recent trip in 2008, I went to my first pro baseball game and though not a fan of baseball, the setting was beautiful, as the stadium in on the Bay and it was a typical sunny California day . .
As for Alaska - I went on one of those 7-day cursies with my mom several years ago and it was amazing! Since we were out on the sea/water, we got to see Orcas and blue whales in the wild, in groups . . seals jumping off ice-bergs and even dolphins - at one piont, we were in the dining hall and we saw dolphins from the large windows of the ship . . .but in general, the small towns in Alaska are delightful andn though it was wet and damp while we were there (reminded us of our own non-summers in Oregon), we met some nice people (some young adults included that were working there), so in short, Alaska is another place I would recommend - it's like Allah's untouched place out there, the famous glaciers are amazing as well to say the least.
Maybe this summer when I get home, I could put up some pictures if I can scan those in to the computer, as they were taken before the digital camera was that big/before I bought one, hehe.
PS As I said, I'm from the beautiful
Pacific NW, so come visit Seattle and Portland next time 'round!
