I assume no liscense, but he had them in a group around his truck writing something out. He cleared the lake quick! He also warned the gal with the off-leash dog that it needed to be leashed(thank you!) and that no beer was allowed in the park. He covered it all, swept in fast. One thing I did learn, is that if you are fishing together with someone, family,etc., all fish must be seperate. Never knew that. So what, if you are in a boat-you must keep 4 different coolers for 4 people? Anyhow, it was a pretty small lake, so expect them to be everywhere and checking. And, the worms got the fattest fish. The spinners got lots of bites from the small fish.
