I started from Moissac in March of the year 5 but, strangely enough, have absolutely no memories of Aire-sur-L'adour!!
Don't know if any of this will help .....
That evening - Saint Antoine was a farmhouse, E. Dupont, and also a gite d'etape but they weren't doing food, though friendly. When I arrived at Lectoure the refugios were still closed but I found a hotel/restaurant at the bottom of the hill on the way out of town. Cheap and comfortable, the St Jacques de Compostelle. At Condom I stayed at the huge municipal and it was rather good, though echoey as it was empty but for two other pilgrims. Condom has to be the best place in the world to send postcards from!
At Eauze I stayed in the wonderful municipal gite, felt quite medieval - I picked the key up from the tourist office and put it through the letter box when I left.
Nogaro ... errmm ...municipal gite - remember nothing about it!
Next day the town I stopped in - both refugios were closed and the hotel was closed for a refit .. had to walk on to the municipal at Miramont - a 45 kms day. Vastly improved when the mayor turned up with a bottle of fine wine to toast the peregrinos (there was a young American couple there as well - they worked in Japan and were sweet but I think resented me being there as they had it all to themselves until I arrived, spoiled their frolics I think!).
Next day was a short one, to Arzacq - the only refugio there, was excellent, huge place, I was given my own room. Run by a gay guy who I think was "the only gay in the village" (English/Welsh joke) who seemed rather lonely and talked to me lots.
Next stop was at Arthez le Bearn - terrific refugio, municipal - asked in a bar and was directed to it .. old woman across the road had the key, was an 'ordinary' house that the council had done up as a refugio, well appointed with tea and coffee in the cupboards - provided by them. Two council officials turned up with clipboards and asked, as they had only just opened for the season, if everything was ok and how could it be improved. The community had spent money doing it up and wanted pilgrims to be happy there - delightful.
Then Navarrenx, Gite etape - ah, but I have gone too far!!
