LOL, I went to SES with a board, skis, poles, and a single boot in my snowboard bag 49#'s :)
And I third the curbside check-in, it's worth a try. My buddy got a whole huge duffle bag on as "skis and boots" with that outbound from Chicago (you know, we're pay-to-play here...) but it didn't work so well in Aspen, they we're like "yeah a boot bag OK but not a big duffle full of stuff"
