Denver Sluice and Sluice House

"Not another house within sight - oh, yes - one cottage about two miles further up the bank. Boo! Enough to make one drown one's self in one's own lock. Hullo! what happens to the road here? Oh I see; over the Drain by the bridge and turn sharp right - then follow the river. I do wish everything wasn't so rectangular in this part of the world. Hoops-a-daisy, over she goes! There's the sluice keeper running out to look at us. I expect we're his great event of the day"

Don't follow Dorothy's maps, you will only get lost! ;-)
