NW England Mesh Looking for tunnel link to wider mesh.

Hi all!
We have a mesh network in the North West of England connecting the towns of Rochdale and Blackburn and are looking to connect to the wider mesh to help expand our capabilities and coverage. We feel that many more local Hams would potentially get involved with the connectivity this would provide.  If anyone feels they could help, I, and our group would be most grateful. Please do not hesitate to PM me if you feel you can help.
Best Regards
