"Can one wear a Campaign Hat with a Venturing Uniform?"
Don't know. Don't care! I do as Advisor.
The color takes some getting used to what with the green (not khaki - sorry not TAN) uniform.
And I would LOVE to find a real, honest to goodness surplus Army hat that fits and use it instead. Or be able to afford the Stetson brand. BTW,check out old cowboy photos - the did wear "campaign" style hats on occasion. Seems to be more of a mountain wear than Plains, but that's just my opinion.
I agree with other who feel it should be (a) standard issue for all SM-types, (b) better quality, and/or © cheaper.
I disagree with all those who use various chemicals and whatnots to "protect" their hat. I don't, just use the press (used Mountie press off eBay). But then the "official" hat is crappy felt so maybe it would be better to use the chemicals - I just haven't had to. But then, if the hat were good felt, it would be from beavers who are normally wet!
Definition of a Drugstore Cowboy: someone who covers their $300 100X beaver felt had with a $10.00 plastic garment bag hat "protector".
PS: sorry about the rants . . .
