Of course, of course. The NVA wore pith helmets. And Aussies fought 'em too, with considerable success and valour. Don't suppose anyone brought their kilts with them though. Had Uncle Ho's boys heard a kilted unit was facing them, they'd have thrown in the towel sure enough. Foreign Legion - no problem. US Rangers - nothing. Australian SAS - eat 'em for breakfast. Highlanders? Now we're in trouble... [with no disrespect to those fine special forces units]

What I wouldn't give for some blistering sun though... We have six months of winter here, then two months of rain, two and a half months of insufferable insects, and about six weeks of what-its-supposed-to-be-like but usually isn't weather. Despite floods and cyclones, they don't call Australia "the lucky country" for nothing.
Cheers, friend.
