Vermillion, SD to Lewis and Clark State Recreation Area in Yankton, SD- Day 10/11- 50.81/0 mi.

Key words: Hot and Windy
The temperature today soared into the upper 90's before we arrived at our destination and the wind was from 25-35 miles per hour. It was a crosswind, not a tailwind. It was very difficult to keep the bicycles on the road at times. The terrain was very flat. The ride itself was uneventful if you call riding in the heat and wind uneventful. We stopped at Ma and Pa's Convenience Store for delicious burgers. The owners were very helpful, even calling ahead for us to get campground reservations for the night. We got the last electric campsite available. This was a huge campground with nearly 400 sites and lots of things to do. After arriving, we spent an hour or so swimming in the reservoir behind the dam on the Missouri River. It was so windy that there were 2-3 foot waves on the gigantic reservoir. We decided to take a rest day and spend a second day here. Well, we got plenty of rest on Day 11 because at about 9:00 a.m. it started to rain and rained until almost 4:00. We had to change campsites in the rain because our first site was reserved for the second night. It is not fun changing campsites in the rain. We spent quite a bit of time in the tent that day playing Lewis and Clark gin rummy, updating our written logs, and reading some of the materials about Lewis and Clark. We did take one rainy ride about 6 miles to a camping store to get some Coleman fuel for the stove. After it stopped raining, we went down to another beach to swim and skip stones before retiring for the evening.

Seventh Grade Question: This is a math question. Feel free to call Mr. Mohler for help (I didn’t clear this with him, though). Part of the day going to Yankton we traveled a fairly busy highway. Sometimes to prevent boredom, we count cars that pass us, but we often forget how many cars. To prevent this we have devised a method for counting cars on our fingers and let those fingers keep track for us. Now if we used our ordinary "Base 10" we could only count to 10 and then have to start over. But there is another way. By taking advantage of other bases, we can keep track of far more on our fingers. Here is the question; what is the most or highest number of cars we can keep track of on our 10 fingers and what base would you use to do that. Good Luck!! (If this question is not understandable, let us know and we will try to clarify it.)
