Just abit of inside info, find anchor supplies in ripley and get kitted with wellies! cross the road and take a walk down "ripley Greenway" they have been kind enough to put a pedstarian crossing! follow the path until you come across a brick sculpture and then go upstream to find the culvert. I have a funny feeling the lights will be left on for you!. pumps will be running but that is normal and there may even be a ladder to gain accesd down to the stream bed, security is onsite for the weekend just to add fun. this weekend only as the pumps will be switched off monday and the culvert allowed to flood preventing access for another 120 years. not massive but very clean. do not climb the ladder at the end as you will end up on camera and right in front of the office. .......................have fun!!!
