A very good post, and a fine way to come out of "lurker" status!
Also sounds much like my experiences so far. I've been OCing for 2 1/2 years, mostly the south-central area of PA. I have lots of encounters, and all have been positive so far.
I have had a couple that seemed like they could have been negative, they seemed to begin that way, but we rather quickly came to an understanding and the encounter ended positive, and actually even more positive than I had hoped for at the beginning.
Here's hoping all yours are positive as well!
