I can just imagine how many bugs this mini sun will attract. Followed by dozens if not hundreds of bats coming to feast on the easy pickings. Soon to be followed by your dog, a sporting breed, racing in large circles around the campsite while yapping like crazy about the sea of "birds" circling overhead at a 12 foot ceiling. Moments later, followed by your other dog, waking up from his nap and not sure what is going on, but not wanting to miss the fun, starts chasing the first dog while also barking like crazy. You sit and watch this for about a minute all the while laughing hysterically. But then, you too find yourself running in large circles chasing two dogs until you get them back on leash and settled down. Except for the bird dog. He obediently sits by your side but stares at you, then looks at the bats then looks back to you, then back at the bats, then back to you (repeat for infinity) waiting for a release command so he can continue chasing the "birds".
Ask me how I know,...except it was a large campfire and not one of these.
But really YETI! At least offer these with snap on red filters to preserve night vision or yellow/orange filters to reduce the inevitable bug invasion.
