Having a product go out of print is a strange experience. On the one hand, it might mean you've done something right and your product was a success, selling through the entire print run. Yet on the other hand, it's strange to think that something you've worked on and put a little bit of yourself into is going to disappear forever (except, of course, from the gaming tables of all those who purchased it, and perhaps eBay or a particularly well-stocked FLGS).
Why do I bring this up? Because as of this writing, there are only 52 copies of Map Pack: Countryside left in our warehouse, and we don't currently have any plans on reprinting this particular set. That means that when they're gone, they're gone. If you haven't already, hit up the product page and see if your game could use things like a coaching inn, ambush site, or roadside shrine. (The rope bridge, in particular, seems to have generated a lot of excitement.)
