Street Photography: Pumpkin Festival

During a huge street festival hosted by my town, I decided to practice my street photography.  I decided to start by wandering about  to see what I could find. Some people were easy to capture, like these two super heroes above. I asked if I could take their picture, and they were happy to oblige (although the focus is not quite as crisp as I would have liked). I found some other interesting characters as I wandered, like this guy:

And this baby who had had too much pumpkin festival:

But my feet were getting tired, so I decided to follow some advice I read about street photography.  I found a comfortable place to sit and waited for interesting people to come to me. 

The hard part was trying to capture people without too much background distraction, but I did find this pair interesting:

 

And I enjoyed the fun being had in the kids' area:

And my patience was eventually rewarded with my absolute favorite capture of the day:

Aren't they fantastic?!? 
It was such fun to spend a good hour trying to capture good street portraits. I
 took all these portraits with my 50mm fixed lens and my camera set on the "running man" setting in an attempt to be less obtrusive and not spend too much time fooling around with settings.  What do you think of my street portraits? Got any favorites? And do you have any good street photography tips to share?
