K.L.
Solar soccer club has a division based in McKinney and they practice off of Industrial and Airport Rd(SE McKinney)and have a whole complex of fields for the entire club. My son and nephew play on the 02 boys, my nieces also play for Solar and are 8 and 12. We have been very happy with the club.
Manchester is also in McKinney but I think their practice places change according to what day of the week it is. FC Dallas is out of Frisco and wouldn't be that far either. We are a big soccer family, with tons of experience. Let me know if you need any more info or help. Welcome to Texas!
