I've seen some people out on the piers with their stuff in wire push/pull carts. Now, I usually go fishing alone, so handling a crab pot/shrimp trap and all your tackle, gear, and cooler is a bit much for one person to handle. I'd like to get one for myself, but I'm not sure where they can be bought. Can anyone help?

Id check any of the hardware stores, maybe even Boeing suplus.

A lot of those guys use luggage carts. They are light and cheap and some people ad a milk crate using a bungee cord, this doubes as a seat / storage.

Fred Meyers also has some that has black milk crates built into one that folds. I believe those about $19.99

You can also use those rectangular grocery carts that ride on two wheels. I see all the old timers using them all the time, they are totally decked out with rod holders and different storage compartments.

There might be some grocery carts available near Shorline when the homeless camp moves to the burbs.

Try a garden cart from Lowes or similar.

here you go, boaters world has some for 24.99, fred meyers has it for 19.99( a little smaller)
