Well….
After high action night it was time to go. Going to pull up anchor and Thunk…. the stern anchor would not budge, stuck in 8 FOW. After trying for close to 10 min motoring and pulling in every direction it would not budge or pull loose.
Its been a long time since I’ve had to cut one loose. That makes 5 that the MN river has claimed from me 
Project for the day…. buy fluke anchor, modify, add window wieght’s and test tonight.
