Taking a Summer Vacation

Scott Rassmussen tweeted Thursday:  "38% Plan to Take a Summer Vacation This Year."  His poll results are here, and they are interpreted as as a sign of slowed economic recovery. 

I'm not so sure the problem isn't in the polling instead.  Here's an example:

My family is going to Minnesota this Summer to see my mother-in-law.

If Scott called my wife, she'd call it a summer vacation.

If Scott called me, I wouldn't.

I suspect more people are going somewhere for the Summer, but they choose to call it something other than a vacation.
