I love DaMoors in Glendale. Great service and selection.
In Hannover, Germany, my favorite is Engelke. Sadly, I didn’t make it up there on my recent trip, but they have a great selection of Pikeur stuff, really quality tack as well.
Sadly, Barrington Saddlery closed a few years ago. I had only been there a few times, but what a classy place. DH has family in the region, and it was a long drive down there, but so worth it. There was another store in Libertyville that was more convenient to where my in-laws lived, but it’s now a Dover.
