You will have to convince the management they should build one and spend the money on rails and manpower maintaining it. You will need numbers to do it aswell, through email. we did it last year at thredbo and this year they spent $5000 on custom rails and they groomed the park everyday at 9:30. and the pipe was cut when it needed it by rider standards. If you post the site of your resort(s) I am sure a few people will do a friend the favor of saying'I really enjoy your resort but feel that it lacks the freestyle terrain park of some other resorts, will you be building one this year that is up to the standard set by the other hills, coz its almost time to purchase a seasons pass.' or 'me and my buddies wanted to get a season pass at your resort but are wondering if you will have a terrain park for us to ride, coz a seasons pass is pricey and i dont want to spend all season with a bad park that is small and shabby'
so post the site if they have one and ill happily send em some words.
ever wonder if iliterate people get the full effect of alphabet soup???
