Hey, I have a message. I didn't know.
I don't live down the Cape. I own a timeshare at Briarwood in Falmouth, so have been going the third week in August for the past 7 years. I like Falmouth, it's more quaint than the crazy Hyannis area. I've always lived about an hour from the bridge though, so I've been going for weekends since I was a kid (mostly in the crazy Hyannis area as a teenager).
A few years ago, I did toy with the idea of moving down there (I tend to think like that the fourth week of August each year). Will probably retire there someday...
I actually love the Cape off-season, when it's quieter (I'm sure that's why you like Wellfleet).
