Town's Sunday construction ban could affect do-it-yourself work

UPDATE: Town's Sunday construction ban could affect do-it-yourself work - Monday, 10/17/05: "Spring Hill aldermen are facing a decision over whether to go after do-it-yourself enthusiasts who violate an ordinance banning construction work on Sundays."

I don't like any law that limits any activity on Sundays. Why is it just the Christian sabbath that is banned, why not Saturdays for Jews and Fridays for Muslims? What is the holy day for Flying-Spaghetti-Monsterism anyway?
