when conditions allow, i.e. when the atmosphere is stable, no pressure drops, no strong wind or rain in the area, If conditions look good (low or no wind), get there early! The Congress bats are giving birth these days (average date of birth is June 10th) so flights will be diminished, unless a north front moves through that stirs up insect activity.
