Mattp, I'm hardly wrapping myself in the cloak of patriotism here. I'm sure if they'd put up a banner for Walmart, people would be just as torqued, even though, arguably, a lot of people here probably get crap there for climbing trips.
How many climbers have I gone out with who stop at the McD's in Leavenworth? How about banner for them? Seems that's part of 'climbing cluture'. Where do you draw that imaginary line? I suppose if the CEO of backcountry.com made some obscene salary that exacerbates the rich/poor wage gap, there'd also be objections to them having ads, even though they're serving this 'climbing culture' you keep talking about but never define. Seems to me climbers are a more diverse lot than you seem to think they are. I'm sure that if the ad had been for the Peace Corps, there'd have been no objections, right?
I'll repeat three words mentioned above: pecunia non olet.
