does anyone know of a company/store that sells portable livewells? i am looking for a well that is big enough to keep 5 bass alive on my flats boat. i have a livewell on my boat, but it is way to small for 5 bass. any suggestions would be greatly appreciated.

Triton21 gave me this idea.  I have not done it yet because I have been really busy but if it rains and I can't get on the water this weekend I am going to try to make one of these one saturday.  I copy and pasted Triton's exact post below.  Hope this helps.  

"Jaskoh, get a cooler, as big as you can haul in your trunk, a bilge pump, hose to fit it, and a piece of pvc pipe and cap, cap one end, put the hose on the other, and 12 volt battery.  take a hack saw and cut small slits or a drill and drill holes all on the same side of the pipe,  mount the pipe above the water line with the holes down.  You can buy a kit from Bass Pro to do this if you don't want to do the leg work to collect the parts.(cooler livewell kit)  If you don't want to get an extra 12 volt Battery you can run a long wire with a cigerette lighter from the trunk through your window to the lighter plug in your car.  A 48 qt cooler should keep 15 to 20 10in bass alive for that 35 mile trip.  

This also works as a livewell for a boat that doesn't have one.  Will also keep bait alive.
