I called around to confirm July walk-on days around London. I found 3 (probably more, but 3 is more than I expected anyway): 8/7 Campaign Paintball https://campaign-paintball.com/ 15/7 Mayhem Paintball https://www.mayhem-paintball.co.uk/ 22/7 Driverwood https://driverwoodpaintball.co.uk/ Campaign seems to do 2nd Sunday of the month and Mayhem the 3rd Sunday. Driverwood was doing 4th Sunday but is switching to the 1st Sunday in August, I think, to deconflict with competing events. I'm planning on the Mayhem and maybe one of the others. I'm returning to the sport after years away, and never played in the UK. If anyone is planning to go to one of these or has thoughts about whatever, post!
