There is a big hill on the way to the elementary school.   At the first sign of warm weather the bikes and scooters come out of winter storage.  On the first nice day of spring a group of 8 boys rode their bikes to school.  When they got to the hill they all had to get off and push.  The next warm day the group had lost several riders.  The 6 who were left still had to push.  We have had a few warm days now and the group is down to 3 who ride their bikes every day.  The last several days the boys have been able to ride all the way up the hill without stopping. I asked the first boy up the hill today where all the other guys were.  He said they didn’t like pushing their bikes up the hill so their moms were giving them rides to school. He and I agreed that even though it was hard work it was getting easier and the payoff of getting to go down the hill FAST was worth the effort.  That is how I feel about down hills on my bike.  I love them, I love going fast.  It IS worth the effort.
