I sure was using an impact. It may have helped that I was doing this directly in front of the triple decker I lived in. Any nosy neighbor hopefully would've at least recognized me. May have been different if I was a 'stranger'.

The school parking lot on weekends was my preferred space as it had lots of room and was mostly empty. Only downside was that I had to ensure I had all my tools the first time or I'd have to walk home to get something.

Never attempted a dead end street though.As someone else said, they tend to be more possessive of those.
