I've been thinking about going to Arizona to see amazing sights like that :) But then I learned that scorpions are everywhere in Arizona, and that's sort of ruined it for me, lol. But I'm sure it's an awesome place to visit for people who aren't afraid of things like scorpions. :)
I travel London in my mind all the time. I've lived there for 5 years, but I've been wanting to go back for the past few months and I travel all the roads in my mind.
