Blipper Spotted. GX1, Leitz Summicron 35mm V4.

We were down by the river for a fine summer evening, this time in search of a stroll, a sangria and any Blipping possibilities which might present themselves. There is a nice stretch of lawn in a park behind the Kennedy School of Government and I found this group relaxing. Obviously I spent too long composing the shot and they spotted me.
Oh well, no harm done. Just have to be quicker...
