My biggest contribution to the "ski cheap" thread last year was the GOOG "Ski Free" gas station map I created to use with GPS on a smartphone. Took me several hours to create the dang thing, but it will be easier to update with new stations and remove non-participating stations this year since I have last season's template. Why in God's name the company running the promotion doesn't provide this (obvious) tool themselves I have no idea, but theirs is my favorite money saver.
