From the timings this looks to be the intriguing stop at the end of the route, where the road formerly continued across the old airfield.
Whilst the locals do consider it Brentry, or even Southmead, technically it is actually in Filton as it is across the boundary in South Glos, not in Bristol. The only way of accessing the stop though is from Bristol. The binmen hate this small patch of S Glos which is a mile and a half from the rest of Filton/S Glos, through Bristol.
We let a service 13 heading towards Broadmead come up and do it's double run before boarding the next 13, which is doing the double-run in the other direction.
We therefore depart on Stagecoach West service 13 at 1829, alighting at Shirehampton, Hung Rd at 1903 on Wednesday.
