Day 22:  Lauterbrunnen to Koblenz

Just a transit day.  We stopped at Heidelberg, where to our delight another Oktoberfest was going on.  Then we stopped at St. Goar for stein-shopping and wine-tasting.  Kinda boring.  At our hotel the bar closed early, and although there were continuing room parties, I went to bed and ended my streak of consecutive drunken nights at 21.  I think the previous record was 9 or something.
