I'm in Grimsby, used to work in Scunny ages ago so no up to date info.
There are hills if you know where to look, ok it's not Wales or Scotland sized hills, but still enough for a fun ride.
I think that a 'welcome' ride in the area might be in order (although this statement in no way means I can organise it as I don't know the trails round Scunny that well)
The other Scunny lads will be able to help you more.
