We are in North Yorkshire, not very helpful but we do have our own Mini arena for testing (10mm Poly walls, 5mm roof, 4mm Steel frame). If you are ever in need of a hand just give us a shout and we may be able to work something out.

As for events, I believe Barnsly is the most northerly HW/FW event run by Roaming Robots. We did hold an open BW event at the York STEM center. Still not close but better than London.
