Beware - they are out in full force now that school has started! I have seen two officers on bikes but luckily they haven't gotten me! :-) I've been wanting to snap a shot of them in action for a while but I'm always driving or without the camera. Plus it's tricky trying to discreetly snap a shot while they are stopping someone. This is a favorite spot of theirs on Cedar near Guadalupe. So be careful and you won't have a problem. There's a school zone right around the corner and people often don't slow down.
