PITTSBURGH, Pa. - With Mitt Romney spending the week at his multi-million-dollar Lake Winnipesaukee vacation manse, President Obama reminisced about his humbler family vacations as a child - part of his attempt to better relate to working-class voters during his two-day campaign swing through Ohio and Pennsylvania.

"I remember my favorite vacation when I was a kid, traveling with my mom and my grandma and my sister, and we traveled the country on Greyhound buses, railroads. And once in a while we'd rent a car, not that often, and stay at Howard Johnsons," Obama told supporters at Carnegie Mellon University.

"Didn't matter how big the pool was; if there was a pool, I'd jump in. I was 11 years old, and I was excited just to go to the vending machine and get the ice bucket and get the ice," he told the crowd.

Not exactly jet skis on Winnipesaukee. Hint, hint.

The president continually said that his story embodies the American Dream.

"None of us came from privileged backgrounds," Obama said of his and the First Lady's families, in a not-so-subtle jab at his wealthy opponent.

"None of us had a lot of wealth or fame. But what we understood was that here in America, no matter what you look like, no matter where you come from, no matter what church you worship at, no matter what region of the country, if you are willing to work hard, if you are willing to take responsibility for your life, you could make it if you try here in the United States of America," he said to applause.
