I am in a fish club in Boston, and we have once a month meetings where all of us fish geeks get together and swap corals and critters... I was using one of those Coleman picnic-type coolers to carry my stuff in, but that was so boring...
Hubbles works at an AIDS lab, so he has access to free styrofoam coolers, yay! Here is the plain white cooler.
I had to make a hole in the lid because you can't leave the critters too long without air -- I fed an airline through the hole in the lid and connected it with my battery-powered air pump.
Here is the body of the completed bag without the cooler in it
Here's the bag with the cooler in it, I made little button/snaps on the sides to make it easy to get the cooler in and out
Last pic, I put pockets on one side -- One pocket to hold the air pump, one pocket for empty ziplock bags (which are handy at these meetings), and a small pocket for pens/gum/whatever
That's it! The big once a year auction is tomorrow, I wanted to be prepared
