So I stopped at the park today after lunch. Thought I would get out in the sun for a walk while it was out. Beautiful afternoon. I like the quiet end of the park, away from the kids playgrounds, usually just a few people like me stopped to eat lunch parked there. There was a gathering at the first covered seating, so I passed on, one of the local homeless parked on a bench further down, so I passed on. The last area had a family playing games and picnicking. I parked across the way. I'd noticed a middle aged man on a bike about half way down. When I step out of my truck I see he's stopped just a few yards back behind my truck. He's whistling a tune and hanging around. I take a few steps away from the truck and when I turn and look back he's still hanging out there. I stop and look out at the river, still withing visual range of the truck, I still hear him. Now he's riding this way, when I turn around to watch him he rides slowly down a trail along the river still whistling. I've got a bad vibe, decide I'm not just paranoid because I feel like I'm being stalked, and sized up. I go back to the truck, listening to the dude on the bike slowly work his way back to where he was before. I get in the truck. Soon he's popped back up on the road just behind me again. I start her up and turn it around. Now I'm rolling slowly after the guy on the bike. Not close, just headed his way. He doesn't even make it past the first picnic area before pulling over. I head on out. I'm going to keep an eye on the community policing section of the paper for a few days. I'm aware of the homeless population around town, know a lot by sight. Our church feeds them. I know they have violent and mentally unbalanced persons if not out right criminals within their population. This guy I'm watching for. Things to learn. Be aware of your surroundings. I had my eye on this guy before I exited the truck. I knew where he was even without the whistling. If he hadn't been alone I wouldn't have even left the vehicle.
