Kent is not such a desert. Within 20 miles of me there are (at least)

Maidstone - Folk and acoustic music
Rainham - Moore or Less, Folk at the Oast, and an Old-timey session
Rochester - the Good Intent
Lower Stoke - My own (winter only) sessions at the Nag's Head
Eltham - Folkmob
Orpington - Orpington Folk club and Fridayfolk
Dartford - Dartford Folk Club
The thing that replaces Knapp's Valley
Sheppey - Folk and Blues
Snodland - the Bull
