Haha I went to Vegas, San Diego, and Tijuana in Mexico too. San Diego is lovely, Tijuana is a...... hole, putting it nicely, and Vegas is awesome, but much too hot for me! I wish I had been there when it snowed a couple weeks ago!
Also, Iceland is a beautiful country. Haven't had the pleasure of going yet, but its really lovely. Other than the dead economy, but thats a recent thing. =/
