One of my favorite sites on the web was TopoZone dot Com but now I have learned that they have changed their business model completely -- now they want $50 a year for me to use the site. I have no problem paying for something that is useful but I am struggling to see how a subscription would be money well spent.
I am mostly interested in NH maps. When I tried out the "new" Trails dot Com (which purchased TopoZone), the sample NH trail map that I ended up turned out to be content from a book that I already own...
I am fairly certain that everything that Trails dot Com would give me for my subscription would also be easily obtained from the books and maps that I already own. I think that a lot of potential customers will make similar conclusions.
Thus, I think that Trails dot Com made a mistake, and that they are in for a pretty rough ride.
Oh, by the way, if you are looking for a good NH topo map, I think that the ones from Map Adventures are very very nice.
