⏩ It's Forward Friday!

This week we are highlighting good news in the fight for sustainable transportation in Maryland. Montgomery County officials recently announced the completion of the nation’s largest transit depot microgrid located at the David F. Bone Equipment Maintenance and Transit Operations Center in Derwood, MD.

This will aid Montgomery County and the state of Maryland in progressing toward clean transit for all.
