Yep. But things vary quite a bit regionally, and even more town by town or neighborhood by neighborhood. They're throwing up 6000 sq.ft. McMansions like nobody's business around here the last 20 years, so while I'll admit this place is definitely above average on size, it's not exactly rare or unusual.
If I recall, there are two guys on this forum over 10,000 sq.ft.
Oh... and the most important bit of news: the spousal unit approved the wood shed project. Going to the township next week. Thanks for pushing me in this direction, begreen and others.
