I was on the river today and saw a blue fishing yak that looked alot the one pictured. I tried to get close to check it out without being to obvious, but by the time I got over closer , he was getting out of the water and walking up the ramp. What caught my eye was , he had a yellow paddle just like the one in the pic. I don't know if his paddle was stolen with the yaks, but it was a blue yak with a yellow paddle. I hope you catch them. The guy had greyish hair, maybe 50ish.
