Pretty sure I mentioned this as well.... that article talked about dumping an old car into a break to block it.
We bought that land in 1952. Sold it about 12 years ago. During the time we owned it a winter did not go by that we didn't work to strengthen the levee. Any time an old business was torn down in this area we took the concrete and put it on the levee back. Lined it with tin. Anything we could get our hands on... which included..
many old cars. I have no idea how many, over the years... but that levee bank is lined, for nearly a two mile stretch, with many classics cars. Our old 55' Chevy is there. My cousin sent me an email in March saying her grandfather's 42' Chevy is there as well as a late 40's pickup. Most likely every family that lived here in the 50's has a car up on that levee. - JamesJM
