Bike Cart update

I've used it about a week. Already had 2 slow leaks. I replace the tubes, and filled them with "Slime". Hopefully, it'll take care of the leaks caused by the puncture vine thorns that are endemic to this area. I attached the extension to make it 8 ft. long. This is a little awkward, but useful for really long loads.. When it's at 64 inches, the wheels are at the back, and you can role it like a dolly when it's unhitched--very convenient.
