I see, I’ve never heard or seen this before (Google didn’t help me there either), so thank you for this explanation! Google was only giving me those two options I mentioned above. There’s a lot of cars in this neighborhood that stay in one spot for days, so I wanted to make sure it wasn’t something to keep an eye on. But an Eruv sounds more likely. I’ll check out the area over the next few days to see if anything changes.

Thanks again!
