ME TOO! We had that very situation in our neighborhood - which is Non-HOA. We're on nextdoor and a call went out about one of our neighbors who is in a wheelchair. They said he would never ask, but it looked like he needed help. One day a group of us descended on his front lawn and took care of things. While I realize someone could stupidly go after you for trespassing (we didn't go into his back yard) - it's still an act of kindness to help out.  I HATE HOA's!
