Very nice! Did you also visit the small village of St-Julien? There, this first gas attack took place, also, slightly north of it, is Kitchener's wood, where also a lot things happened then, during second Ypres. I am also going to visit Ypres, and the salient in a few weeks time again.
I visit the salient for about 23 years now, so I know the place well.
I like doing long battlefields walks, taking in all the history there. There are so many things to see, but sometimes you have to get off the beaten touristic path, to see all.
