Ideas......anyone?

I know one person has left comments (and I appreciate it) so this might just work. If anyone is following this yet, I'm in need of ideas for photographic subjects/techniques. I've taken just about every different route to work I can think of looking for photo opportunities. The recent trip to Yellow Springs was great, and maybe I'll be back this weekend for the street fair. But soon flowers will be gone, leaves will have fallen, and nature will be bare. I know there is a lot of potential in winter landscapes, but I'm not feeling that right now. Maybe once it gets here I will be in the mood. But for now, besides the obvious wait for the trees to change, if anyone has some suggestions of something for me to try, I'd love to hear them. I would like to watch people and snap things that catch my eye, but I don't really know the etiquette on that.
