Flash Location:
Area is an uncultivated right-of-way under power lines in an established suburban development. Area had not been mowed prior to event in at least a few weeks. Annual event for my son and I to go to this location specifically because of the number of observed fireflies. Fireflies observed sparsely in the surrounding area (1 mile radius), but this number in this concentration unique. Will attempt to upload video again shortly.
