One of my concerns is enforcement.  If a bill mandating all new homes have fire sprinklers, there will undoubtedly be language addressing maintenance.  So the gov't will tell us, again, what we need to buy...then under what conditions we should buy it, then tell us that if we don't buy it, we'll be fined.  Will we then need a separate power source to run the pumps that make the system work?  AAAhhhhh.  Solar or wind power!  It will just be more govt in our lives until the next time.
