Here is another Power Down Challenge event, in addition to those noted in last week’s issue of Almanac.

As part of the 24-Hour Energy Reduction Challenge, turn off your lights, unplug your devices and head outside for a Zumba class, March 20, 11 a.m.-noon, at the Picnic Grove in Penn Park (by the picnic tables).
