----------------------------Original message---------------------------- Now that the 15' topo has been discontinued, I wish to offer this view of the not-too-distant future. Last Friday, I went to the Rocky Mountain Book Fair, a yearly sale of books, maps, etc. that is sponsored by the Colorado Antiquarian Booksellers Association. One map dealer had 15' topos (mostly Colorado) for sale. The going rate for these older topos (1890 and early 1900) was somewhere between $15 and $25 EACH! Has anyone locked up their 15' topo collection yet? Does anyone have plans to do so? Just curious. Linda Zellmer
