Its a chilly day in northern Florida as I am in my favorite winter "jacket". Cotton hoodies are my comfy way to stay warm until I do something to take it off to reveal a leopard print one piece once I get warmed up by means of blowing and the sun beam shining into this tunnel.
I have my handy dandy hand pump to help me inflate and pop each balloon I pick from my stash.
Once the first loon explodes and the echo is so unbelievably long, loud, and amazing. I cant get enough of making more balloons burst into as many shards as possible. I get warm and strip out of my hoody to pop more and smile bigger bigger with every hand pump to pop.
I do think this bridge tunnel helped me hear the longest and loudest echo ever. I think you will agree.
