I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Car park at Orton Lock and cross railway tracks and you are at the River Nene and Orton Lock. Plenty of fields to TOAL.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 20/03/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
