My kid ate most of my ice cream, and then most of her father's when he finished his ride. It was tasty, indeed.

I did the 100K two years ago, with my husband, and he assures me that you miss all the good stuff if you don't do the full century. There was some pretty country on the 100K but mostly just, you know, dirt. Flat dirt. The 50K (which I have done twice -- we rode it four or five years ago, three days after I got my road bike) is all the least interesting parts of both rides, plus some time on the bike trail. Putah Creek Road is the only part that's pretty.
