Hi Judith, To answer your question, "How do you get a topography map"? I pick them up at Rolla, Missouri and save postage. But you could call 1-800-USA MAPS, if you prefer; their catalogues are free and they will tell you what you need to know. The maps that are 1:24000 cover about 7 miles by 9 miles. Maps are available for all 48 States. Judith Fisk wrote: > > Ellwyn, How do you get a topography map? > Thanks, Judy -- Ellwyn L Worley
