I live in a fairly rural area, we have a 'problem house', not with cars sitting around but it is just an eyesore, when the lawn gets mowed which is not very often, they actually mow around the toys and anything else that is in the yard, they actually painted the house once and didn't move anything in the carport, just painted around it. They dug a pond in the back yard and left the hole open with dirt piled up for months, the property has accumulated daily fines for years and they know how to manipulate the system, there is no mortgage so the county cannot really take the property,
There are several 'car people' in the neighborhood including myself, there was a conversation once about a car in my back yard between two homeowners, one that just bought a home within a few months of the conversation, they were told to come to me and explain their concern, never happend. If it had I would be willing to come to a compromise. That's how it should work.
Now in regards to the eyesore house, I personally talked to and offered to 'help' them clean up, they didn't care and needless to say it was a short conversation.
He has called me (yes he has my phone number) and asked for my help with a tow a few times and I did help him on a couple occasions, I never asked for payment, he has offered and promised to pay me , this never happend, I will no longer help him and have told him so, we remain cordial but he knows I am not afraid to say no.
All you have to do is look at California history, I've said it before, some people have therapy dogs, they have dogs in therapy, what's that tell ya?
