What are some cool freediving places around here?

Wirth Lake on the border of Minneapolis and Golden Valley, just south of Hwy 55, off Penn Ave not Wirth Lake Blvd.  Go in at the boat landing or swim area.  There is supposed to be an 80 ft. deep hole near the water bottling plant....lots of old bottles at the bottom...bring a light...Once the silt is stirred up it gets very dark.

Christmas Lake off Hwy 7 in Excelcior....Gin clear and 80 ft deep, easiest accesed by boat though, the milfoil is thick between the access and deep water. 

You could also try Lac Lavon in Burnsville/ Apple Valley.  Water's not as clear as Christmas, but the swim is easier.  I've dove it to the 17' bottom but didn't find the platform that WeatherPaparazzi had mentioned in his post.
