Have always had problems trying to get rid of "free" stuff. And to make sure someone that can use it, gets it I put a price on it. Started that when I had five 20" bikes that I had plans of using the wheels and chains for a project that never found time or motivation to do. Put them out front with free sign. Nothing after a week. Took them off lawn for couple days and then back out with $40 for all. Guy stops next day with couple kids and asks if I would take $25. I said sure, kids were jumping up and down, happy to have them. Two of the bikes worked great and the others, well could get enough for another one, maybe two. Loads them up, and starts to take out the money. Told him never mind, just glad to see them going to someone who would use them instead of scrapping them. Couple weeks later, I'm out front doing some trimming and the same guy stops by with a six pack. Here. thanks for the bikes. Kids are having a ball.
Why scrappers never picked them up? Well probably cause junk yards, because of recycling fees, charge a per tire fee to take something in that has tires. With the bikes, the small amount of weight, not worth it.
So now just like a flea market, I put a small price tag on everything which tells folks it has value and most stuff moves quickly. People that can use, or need, stop. And getting folks to stop is the key. Scrappers go on by. I know, there are always folks that will make up a story, but what the heck, if they go to that trouble then so be it. All I know is that it gets stuff out of my way.
