Hello, Does anyone have any suggestions on a lake or reservoir to do some roll practice in with a friend. Would help to have a solid floor to stand in and assist etc. Yes, pools are nice but hard to schedule around. I'm located in Boulder, and my first thought was Boulder reservoir. But F__ that place after daily fees, boat inspections, and registering each kayak for 40 bucks. What the hell basically. Thanks for any help or suggestions. ~Jh
