Good fun BUT very dangerous you could easily lose your bike, get it stuck 8 inches or less in that sand/mud and you will never pull it out and could easily get stuck yourself. It looks like minky has read his tide tables and knows his stuff but Morecambe bay is not a place to mess with. I have fished that area for thirty years and have had a few cold sweat moments. If you go past your ankles in some areas you cannot pull your feet out, and may have to lie down and try to get you feet out of your wellies. My father lost his best friend off Grange when he got stuck in the sand and the tide came in and drowned him before help arrived. Although minky was on firm beach mostly, some of the gutters you drove past are deadly. Around Walney a big tide is 10 metres and come in at a fast walking pace, get stuck and you could have twenty minutes or less to get free. It only take one soft spot on a seemingly firm beach and its game over.
