Help please! Chicago Neighborhood Bike Tour photos needed.

OK, so this is a bit embarrassing.  I don't seem to have many pictures of my Chicago Neighborhood Bike Tours.  I know that seems ridiculous.  I take pictures of countless buildings, statues, parks, and other points of interest all year, but I do not like riding with the camera in the group, so I never end up with any "on the ride" pics, of the riders themselves, or obviously of myself.  This is pretty dumb in light of how long I have been doing and how often someone has asked if we have pictures like that to lend to their site, blog, paper or whatever. 

Therefore, I am asking for your help.  I need some good quality, high-resolution images from photos anyone has taken on any of our tours that involve the tour participants instead of only the buildings and points of interest. If you have some that you could allow me to use, I would so greatly appreciate it.

These photos would be used for my own websites and to send to press when they ask for pics, which is what prompted this forum discussion.  I would establish a semi-public folder at Photobucket with original file sizes so press could use it in commercial printing. I would of course give you photo credit and ask that anyone that re-uses it does the same, but I doubt there would ever be royalties or payments or anything like that.  I lose money for a living, so that isn't really part of my universe. I guess you can say that your doing it for the fame, alas, not the fortune. 

Anything you have that I can use could be emailed to me at lee@bigshouldersrealty.com and if file sizes are really big, many sites offer big file sending for little too nothing, and/or free trials.  Here's one:
