Blip of a different sort...

I was blipping away down by the river when I spotted this guy, who set himself up to record ???? not quite sure what,
the splashing of the oars of the rowing boats, the seagulls fighting, the ducks chattering, the children laughing, the water lapping onto shore, the cars going past, me clicking away trying to get an action seagull shot? Needless to say, I should stick with stationary subjects.
