Hi guys,
It's been a long time since my last visit to these forums....But with all this lovely weather I have the opportunity to go visit some of the local tunnels. Yesterday we went to Morlais Tunnel, MT, it was great, got some lovely pictures.
Soon a group of us are planning on visiting Abernant Tunnel but I have a concern regarding gases there. Can anyone provide an insight as to whether i need be concerned?
Cheers
