some specifics: it's a honeymoon, prefer non-supported, both in good shape minus his occasionally touchy knees. He's toured, I have not, we can both complete centuries with little drama but would probably prefer 30 or 40 miles a day so we can spend lots of time relaxing. His suggestion was Berlin to Copenhagen, which I agree would be great but some part of me also wants to don a swimsuit and be someplace a little warmer. Then again, if it's August in DC maybe I'll appreciate not broiling in 90 degree heat. We're willing to spend a little money since it will be a last hurrah before trying for kids.
Thanks for any recs!
