The meetings are currently held at the Grady Research Building just west of Ayer.

Ayer, MA 01432

This is the old ice house building by the power dam, but it's not old.
Park anywhere in the building's parking lot and enter through the front (west) door.
In the entranceway, you will see one of the area's finest antique radio and TV collections, all restored and operational.
