Oh, thank you for the great suggestions! I can hardly wait. Our son got this started. He's going to be attending a 3-day computer programmer's conference. I casually asked if he wanted some company on the trip, and he said sure. His Dad & I jumped at the chance. We'll be doing the "tourist" thing the whole week. I'm of German heritage, but don't speak or read the language. I'm hoping info. signs (like bathroom) will be obvious!
