Hello, I've been surfing for some books and ran across a title that caught my attention. The book is "Under 10 Flags, History of Weld County Colorado", by Mary L. Geffs "HC. Privately printed, Greeley, CO (1938)". [doesn't sound like it's in very good condition and he wants $99.95 for it. I assume it is referring to the nations that at one time or another ruled that area ; similar to what they say in Texas about "6 Flags" (Spain, France, Mexico, Republic, Confederacy & U.S.). Anyone know what the 10 were ? David
