Wishful thinking, but the date is set by state law (2 Saturdays before Memorial Day Weekend); late Memorial Day = late opener. Currently there is no active legislation in the MN House or Senate suggesting a change. Maybe if you call your legislators and ask nicely... Here is a good site to pay attention to: http://www.leg.state.mn.us/leg/legis.asp
I am currently tracking the status of the bills pertaining to the Cass Lake spearing issue and the stocking of muskies in South Long, but there are several other bills of interest to sportsmen/women.
