I think I might have something figured out. I have an old cargo type wagon that was pulled behind a bicycle. The attachment to the bike axle with the spring disappeared some time back. Been out in the corner of the shed for a long time. A couple of smaller wheels a handle, (maybe), and a couple of PVC pipes. Should work. I have plenty of time to figure it out. Both sons-in-law and a future daughter-in-law supposed to be here for 4 days, and Ms. Joyce has a Honey Do list from here till then...But, while they're here, some fishin' gonna happen.
