OK, I'm cycling along the Trans Pennine Trail near Fiddler's Ferry, on Sat afternoon near Spike Island, by the river Mersey. You know, the river that runs from Manchester and empties into the sea around Liverpool?
And a rat BOUNCES across the trail. Like a kangaroo. Or a gerbil. Only it's rat sized - say 5-6 inches long not counting it's long rat like tail. Yep I have seen many rats - they RUN. This BOUNCED on it's hind legs. Boingy boingy boingy.
Settle a debate please - what was it?
