We Want Electric Car Charging Stations in MN State Parks and Highway Rest Areas

I drive an electric car, when at home it runs on electricity paid for by wind/sun power. When taking trips there are too few places to charge, but in MN we have state parks using wind and solar to create electricity and many who visit state parks are environmentally oriented and might drive their electric cars if they could re-charge easily......I have also always thought that easy access to charging stations on interstates/highways, such as in rest areas, would increase access and use of electric vehicles!
