The town is Machynlleth, by '30' I meant 30 speed limit so you'd be moving slow enough to spot. It's 18 miles North from Aber so I'd estimate 15.10 earliest arrival. Plenty of caravans still around with only a few car passing places, causing huge mobile chicanes so you may be later than this. Speed traps regularly around the schools in Bow Street, Tal-y-bont and Taliesin so don't succumb to temptation until you see the deristricted signs !
I have polled the editor of the local paper and wait their reply. They cover Aber as well but they have a local edition for Mach. If they are up for it, I'll be back in touch and help co-ordinate a spot for a photo. What the latest that your team will be checking this website ?
