Worth considering this.
I built one earlier this year, works great. It's collapsable if you wanted to stow it away inside the yak. Personally I just walk it back to the car (in case I get lucky and nail that monster fish, it's got to go somewhere!). It's not the most beautiful thing in the world, but it gets the job done. Not the best on soft sand, but its not terrible by any means. I don't have a ton of money, so this was perfect for me.
