ambrosia:A good portion of the submissions to the Look-Out Tower Category are Fire Lookout Towers. I'm not sure if a new Category just for Fire Lookout Towers wouldn't be a huge overlap (I'm guessing maybe half the submissions are for Fire Lookout Towers, but I haven't sat down and counted, so who knows).
I'm not sure what the solution would be. Perhaps, like has been suggested, you could write the Category owners and ask if you can submit these, since they were originally for looking out of but are "closed" now, essentially.
Are there enough of these to warrent a Category just for abandoned/missing Fire Lookout Towers? I can think of only one or two in our area. The original Locationless for Fire Lookout Towers allowed for abandoned/missing, and I logged one where all that is left are the cement footings.
That is my impression as well. Sometimes a category name can be misleading because of the way it is actually defined and restricted. Some things I didn't think would qualify do, and some that I thought obviously qualified, don't.
But, abandoned fire lookout towers is such a small subset, that I don't think a separate category could be sustained. Maybe this would be an example of a "Special Interest" type category as raised by BruceS.
Anyway, I would certainly communicate with the category leader about your concerns/intentions to see if these would be allowed, esp. since they were part of the old locationless cache.
