you can for me but i'm pretty steady on the old treader!
i have 3 possibilities in mind.
first is east ravendale. good points, my parents live there so bacon butties all round. it is also beautiful countryside with a few hills. yay
bad point my parents wont be too happy if 3000 cars turn up!
second. barnetby area. i'm just getting to know the bridleways round here. most of it is farm track rather than single track though. one track is very close to the end of the runway at humberside airport so if you time it right you can get a very close view of some planes. there are some woods but i dont know about access. i will look into it. this could be a decent ride if the woods are legal.
third. could meet in broughton, hit whats left of broughton woods, drop down into scunthorpe where a scunny member can link the various woods. possible downside is it might end up either a there and back sort of affair, or an epic as there are only 2 off road routes between scunthyorpe and broughton that i can recall. also a scunthorpe run would certainly involve a rew road miles.
