The minute your jibbing on their property you are trespassing, they can't do anything as its national forest land for hiking. usually you can't hike on the leased land so possibly their lease finally came into play. as for littering, I can't say I blame them, if people can't be adult enough not to pick up trash they brought in, would you think they are adult enough not to sue or break your shit? at least they were cool enough to wait until other resorts opened.
