This is Hard

So, here we are in Texas......and one night I see these fire flies and I'm thinking "how cool would it be to take some photos of some fire flies flying around with their little lights/bellies blinking?" So, I go grab my camera and the sun is already down and I'm losing light quickly - IT WAS HARD! I think I took like 100 photos of fire flies and got only 2 shots of them with the actual blinking of the belly. I'm sure my neighbors think I'm crazy. Next attempt would be a long exposure with camera on a tripod and fire flies everywhere. Who knows, it could be a cool photo!
