Mountain Bike Riding

My son attends a after school program called Arc.  They take him to leadership workshops and also on field trips that he enjoys.  It is a great program he is going mountain bike riding on Saturday.  He gets to ride on real good fancy bikes and they provide complete padding and helmets.  This is his second year attending these field trips.  He likes them so much that he hates it when he has to miss one.  He says that besides enjoying the adventure he likes it because he is away from his younger sister.
