Today I am leaving for a two week vacation to Europe. My long lost college roommate and I are going to be hitting up Spain and Italy and in Italy Vlad will be meeting up with us for a Gondola ride or two! I am super excited for this vacation and this time will actually be vacationing. We are lucky enough to have someone who will write posts for me while I am gone, Nerdphanie! You all remember her as a guest blogger! Now she is signed on as a two week blogger to fill my spot. She will bring you lots of new bags and goodies to look at. I will be posting sporadically, but not my usual four or five posts a day
