I managed to extract my account of PBP 1999 from an ancient version of Word.

The pub in the square wasn't in Merleac, but in St Martin des Pres, and was called the Auberge St Hubert, it was last open for PBP in 2011, by which time it was a pizza restaurant. The locals had a stall there in 2015. There was nothing in Merleac in 2015, there'd been a stall there in 2011, in 1999 the boulangerie was open at night.
The bridge before Brest is an interesting open-spandrel concrete arch structure, which has a lower deck where a railway once ran. The adjacent motorway bridge is cable-stayed.
1999 also had distance added in for a roadworks diversion, and two extra hours were allowed.
Thanks for all the work in getting us booked into PBP over the years, as AUK's ACP correspondent.
