i got this pvc tube at a gas station because i asked if i could take it and they said sure lol, when theres no snow i just use that wooden box to slide on the rail, astroturf works real good at the end too, some slush or soapy water helps too! go around construction sites and shit and search for some pvc my man! worst thing they say is no .... or just "tactically acquire" it as we say in the army haha
