My little girls are following in big sister's footsteps and are exploring the world of Track & Field. Two of K's high school coaches run a track club during the summer for kids 5-18 years of age. Practices are held 3 nights a week and it's been very hot here. The girls had several athletic t-shirts but 100 degree weather really calls for tank tops.
