You have been to so many places. I feel like such a stick in the mud. I did go to Ireland by myself once to attend an Irish Crochet workshop for a week. Hit Dublin, rode bus to the little village where the workshop was being given, rode bus back, got on plane and left. Dumb I guess not to have ventured out a bit but I am leary of traveling by myself. I have no sense of direction and if there is a decision to be made, I usually make the wrong one. Gotta face facts.
Your trip to Holland sounds just like what I would like to do. I bet I could do that by myself. I flew over the pole to Ireland via Frankfurt, Germany, so assume I could maybe fly on Condor directly to Amsterdam. Perhaps next year.
