Yes, good start.
Jim that reminds of the time I tried to capture a whole bunch of Pennsylvania Bats exiting in full flight through a tiny crack - at sundown. No matter how hard I tried, I struck out. The light was of course dimming at that time of day and the Bats were fast. Bad combo!
In the meanwhile - those Bats were pretty much all wiped out, so I will never get another chance.
