One solution would be to go to the areas where people know and live. One evening we go to Putney - or places near you Irish. The places you know and know we can game. Then somewhere elses area. I know when I play locally, in the places Im comfortable in, I have an awesome evening. Im sure this has enough energy to lift others.
I can understand your frustration with last night - there was no certainty or solid structure. And plenty of walking.
2 people can always stay over mine when we do Kingston. I know all the best places to go. And theres plenty of them, all in a short walk.
Im not trying to sell my area - Im suggesting we go to everyones area, different each week. If indeed the area is worth it
Just because we are going to central london that doesnt automatically guarantee high grade female mixed with comfortable venue.
