It seems settings are harder to tweak, interface is awkward, and I absolutely hate the tabbed browsing feature (even though I know it can be turned off...somehow).I'm not a person who is resistant to change at all, but Microsoft really made too many drastic changes between 6 and 7.

It has a ultra-quiet pad, hydroloc core, and a scratch resistant urethane with aluminum oxide wear-layer (see below). 

Contaminants in the air in our homes and buildings from household cleaners to hairsprays and everything in between have a tendency to react with and oxidize the copper used in air conditioning coils.

I put in water resistant vinyl in my basement at less than $2 a sq ft over here in Maryland.

Finally, there are typically opportunities that I might consider recession resistant.

Word gets around about Heidi's drink now pay later marketing strategy and as a result, increasing numbers of customers flood into Heidi's bar and soon she has the largest sale volume for any bar in Detroit .By providing her customers' freedom from immediate payment demands, Heidi gets no resistance when she substantially increases her prices for wine and beer, the most consumed beverages.

Air takes the path of least resistance, which means the shortest ducts (closest to the air handler) will naturally get more flow than the ducts further away, as Mitch stated.

It there is any situation where the hot can get to the physical ground, and that path is the lowest resistance, it will take that path.The dangerous sitaution the ground wire and that thrid prong is intended to mitigate is when something goes wrong with the neutral connection.

But you are Borg resistance is futile sorry couldn't' resist :mrgreen:

Just so you know for the future, the hardi board or durarock boards are NOT waterproof, more like water resistant.
