Duluth - Lester River?

Does anyone have any current information about skinny dipping in the Lester River or elsewhere?  I'll be in the Duluth area in a couple of weeks and while I'm not desperate to go skinny dipping, I'd definitely incorporate it into my plans if it's available.  Basically I want to know if the Lester River is still used for skinny dipping?  How many people might be there on a week day or a weekend?  Is it a mixed crowd?  Is it strictly a swimming spot or is there funny stuff going on there as well?  Is it patrolled by law enforcement?  Will I have to call my mother for bail money?  And finally, if it's safe and recommended, how the heck do I find it?

Thanks for your help,


Karen
