dude, 24 is nothing, i dont wanna sound like a dick, but dont be such a pussy! you easily have another 10+ years of good park skiing left in you. there are a ton of people in their late 20's/early 30's skiing and snowboarding park harder than the 20 year olds.
im 22 and i plan on going to hood for the next 10 years.
im skiing harder and better than ever, i feel better physically and mentally, than i ever have, so i dont see any reason to stop skiing park any time soon.
shit i just started mountain biking and bmxing(more for mtb practice when im not near a mountain) and im going into it with the plan of learning spins and flips.
i started dirtbiking last summer, and hopefully ill start racing this summer.
the 20's are the best years of your life, dont let them go to waste by using an excuse meant for 50 year olds...
but to answer your question better, id reccomend just skiing the public park and sneaking into the camps parks for a couple runs a day. its cheaper and more fun to just do it on your own. ive dont both camps and public parks.
