I'll bet you wouldn't have thought twice about the second guy if not for the first guy. His conversation seemed pretty tame to me, if all he was talking about was cycling. He might have been interested in you, but I wouldn't worry about it too much.
One time I was in Albany, NY in my little red Beetle, with couple of bikes on the rack and the back of the Bug full of gear, and Arkansas tags. We stopped at a Panera Bread to use the wifi and the restroom. Because of all the stuff and a strange location, my son and I took turns going in the restaurant. While he was inside, I pulled out the laptop and was looking up something.
A man walked up to my car with one of those little cups of water and some bread in his hand. He knocked on my window to talk to me. I wouldn't roll the window down. He was with a woman and getting into a beat up old car. I thought he was panhandling and getting free bread and water from Panera, although his manner of dress wasn't clearly indicating that. But when I wouldn't crack the window he tried to yell through it, and I couldn't understand him. He tried again to get me to roll the window down, and when I wouldn't, he clearly became annoyed and made a gesture like, "WHAT? You think I'm going to harm you?" Then he walked away.
Every once in a while I think about that encounter and I realize now that I was clearly misinterpreting his intention. I feel a little bad about it sometimes. He just wanted to ask me about my Beetle or my bikes or Arkansas or something? Or maybe my laptop, I dunno.
I was just being extra careful. Extra extra extra careful. But now I think I probably missed out on something at least interesting, perhaps entertaining. I'll never know because I jumped to conclusions.
