Replying to Being kicked out

So me and a couple of friends were hitting a rail we set up and some douche bag guy pulled up in his truck thinking hes some kinda big shot and kicked us out because he claimed it was his property and didnt want to get sued. (this was the type of old guy who hates teenagers) We offered to sign wavers saying if we got hurt we wouldnt press charges or sue all he said was no. Any ideas ns of how to be able to ride there without him calling the cops?
