Vote No on Question 4.
Question 4 seeks to increase what people pay in property taxes so that the town will have money to spend on open space and historic preservation. Canton already has enough open space. And, contrary to what some may like to think, there are no historic sites in Canton to be preserved. If there were a worthwhile historic site, a private non-profit entity would preserve it without the need for tax to be levied on every piece of real property in the town.
The Vote Yes people have sent out a ridiculous post card that suggests that the Plymouth Rubber Factory site could be turned into a water park for children to play in. I would not want any children ever playing at that site. I can't imagine that any clean-up of hazardous materials would ever make that site safe.
