I'm in Burnham on sea, just down the road from you. If you have transport you might want to have a look at the "fishing holidays" thread on here, as the water in question is situated in a holiday park, so the chances of getting yer car done over etc is pretty well non-existent, it's not just a hole in the ground sort of place either, have a look and click the link in the thread......
Hope this helps.......
