It was great. If you do it, I'd highly recommend going to Esquelbecq and visiting Brasserie Thiriez. Terrific beer and a nice terrace to drink it in if the weather's good.
I brought back a tonne of their beers when I drove over to race 24hr MTB thingie last year. The bar looks fun but we didn't have the time to hang about.
This sounds spot on for September.
