"That's Belgium"

Funny line in an article in SI, about a recent race in which Lance Armstrong competed. Author Austin Murphy writes: 

"The first three stages were contested in rains ranging from steady to pelting to torrential - and temperatures that seldom rose above 50 (degrees). "That's hard," admitted Andrew Messick, president of AEG's Sports, which puts on the TOC. "I mean, that's Belgium."

I have to say, that's not always the case! It's been sunny daily since Saturday. But the line made me laugh...
