We showed up Tuesday 7:50pm to 8:30pm
The parking lot is a business district however at night no one seems to care.
Its a nice little walk I'd say 2-3 football fields in distance from parking lot to the cave.
I enjoyed the walk more than sitting and waiting. The walk consist of trees hanging over head while bats constantly fly over you.
A family of 4 and a family of 3 sat near the bat gates all the meanwhile you hear runners and cyclist run though river bed.
While we sat in silence I was hoping to see a mob of bats flying out of hell but it was more like a constant flow of about 1 or 2 per minute.
