I tried. Turns out it's a really old guy living there, I don't think he liked me asking questions. He said he doesn't know anything about it, his son has had all the dealings. SO BACK TO SQUARE ONE!!!!Depends on the person there. I would ring bell then stand way back with mask on, and start with "sorry to be a nuisance, but maybe you can help"
Worst that can happen is they hate humans and they whip you.
