These days ? Simple -

(1)I now suffer fron Tintintus, visiting a folk club can be litterally painfull.

(2) Transport - There are some good clubs within South Wales. All of which require me to drive to get to and from. I can not enjoy a Folk Club without a beer or two. And I do not drink and drive.

It was far easier when I lived in Kent, as last Trains ran at Civilized times, ie after closing time.
