Steve,
You might want to get the word out on your Arlington blog that APS school facilities are available for use by the public. APS has a great software tool to let folks see what space is available. Here is info from the APS website.
To view spaces in the schools or other buildings, please go the the link
http://emsweb.apsva.us, contact the facility coordinator for the space you are requesting from the list under Facility Use Contacts by Location or contact Endia G. Holmes at 703-228-6125 or eholmes@arlington.k12.va.us for additional assistance.
