Modular bag - thought about it, had several things in mind and usually grabbed the same stuff anyway. Eventually has 2 bags, my RI bag and my Canal Bag
If i start at dusk we will say I will switch out some stuff after dark then again on my last stop before dawn. Granted 90% of the time it is eels anyway. This bag will be insulated and water proof to keep the ice for the entire night with a drain tube to drain off melted ice water.
