I received three calls for swarms. I asked all the right questions, got all the right answers. I arrived and saw-get this-all three fly away as I set up. Two were waist high and as huge as beach balls. The third was too high and made an audible sound as they left the tree and flew away. Lost lots of gas, spent hours running around, but it was cool to see the swarms take off by the thousands and soar away into the big blue. Tomorrows another day....
