Any suggestions on fields or parks that are available in the Fairfax or Arlington area to hold practices on weekends or any lit fields for weeknights?

Thanks

On the weekends you are going to compete with most of the local soccer teams that have the fields that we play on. i suggest you find a middle / high school and practice there.

Fairfax county fields are still closed for the winter .... except the turf fields ... watch yourselves. our team has been kicked off in the past.
