Pulled across water on slabs of fiberglass

Yesterday I went waterskiing for the first time in over 10 years. My roommate's parents gave her their old boat and she's been going out to the lake for the last few days with some friends trying it out. After I finished up some errands yesterday, I drove out and met up with them. It went well, I got up fine and had one good, long run. I guess it's like riding a bicycle. I forgot that waterskiing uses muscles that do not come into play much in my regular life. The muscles in the top of my feet (extensors?) were sore this morning. I'm looking forward to a summer of boating and skiing. It's good to have friends with boats. Boats, boats, boats. Wheee!
