Tobogganing is a favorite winter activity for kids and even adults. Can you imagine if it was banned？
　　The city of Orangeville， Ontario， Canada is trying to do just that at Murray’s Mountain， a popular tobogganing location （场所）， and has put a “No Tobogganing” sign on the hill.
　　But adults and children of Orangeville are not having it， so they held a “Sled In” on Sunday and tobogganed online as much as they liked to make a statement.
　　“To say no tobogganing publicly is just unfair and such a disadvantage for the kids，” said Rob Stewart， a resident who organized the “sled in” on Facebook.
　　He understands that the city likely put up the sign to stop them from getting in trouble if someone injures themselves， but thinks there’s a much better solution.
　　“The sign should say toboggan at your own risk—I think that’s reasonable. I don’t think anyone expects the town to be liable for what happens when you’re tobogganing，” he said.
　　Tobogganing is listed as the fourth most risky sport for serious injuries in the book Catastrophic Injuries in Sport and Recreation by Dr. Charles Tato.
　　The Town of Orangeville said on Thursday the sign was put up so that it could be easily seen
