About a year ago, I was in the city for a seminar. Doing some caching after a days learnin', I made my way thru a neighborhood to a city/county park. I hadn't ever been there before. My gps showed the cache off a ways in what I thought was out of the park. This park had a circular drive, just make a big loop. As I had pulled in I noticed an SUV parked to my left. As I made the loop, I passed it. So I pull down the drive to the stop sign and make a left. Noting that there is a ballfield below, where the cache must have been, I proceeded to a T intersection with a stoplight. I looked in my rearview mirror and see this SUV behind me. Ok, no big deal. I make a left at the T .... so does the SUV. Ok, now I'm on alert. My plan, initially, was to scope out the park and possible cache area and go back and park where need be. Now, I decide to do a turn around by taking a street, left again. It is a residential area and this SUV turns too. Now my heart is beating faster. I turn again, this time it was into a cul-de-sac. Yeah, so does the SUV. Ok, now I'm ticked. I'm being followed. So I start trying to reach someone on my phone. At the same time I do as I had planned. I pull back into the park and pull my car over and this SUV passes by really slow. I finally got hold of someone and told them what was going on. I then pull back out and go around the loop, to find the SUV sitting there again. As I drive by, the window is down several inches and a hand comes out , sort of waves. I kept on going...and I'll be danged, if it doesn't follow me again...I had given up on the cache as I was NOT getting out of my car HERE! I drove towards a major thoroughfare and pulled into a business, either this person would keep going or pull in too. HE pulls in...I'm ticked big time. I put my window down and he did too. I said, "Why are you following me?!!" He said I signaled him. WTF?!!?! I said I most certainly did not. He left. I left. I was very freaked out. During that confrontation, I had someone on the phone who heard it all. After I got home the next day, I decided I should call the authorities. I figure he was either looking for 'fun' or drugs...or maybe to hurt someone.
