What is the largest domed structure in the world?

AT&T Stadium in the Dallas suburb of Arlington.

Opening in 2009, the facility is 3 million square feet. The Statue of Liberty can fit inside with the retractable roof closed.

That is the where our sightseeing tour started. Jess is a diehard Cowboys fan and had this on the itinerary weeks in advance. Wearing her Jason Witten jersey, her husband Matt, Sally and I joined her on a self-guided tour of the home of the Dallas Cowboys. Tickets are $22 per person.

Often referred to as Jerry World for Cowboys owner Jerry Jones, the stadium is impressive.

From looking up to the world's 24th largest high-definition video screen, to walking on the field for a photo opportunity at the 50-yard-line on the iconic Cowboys star to a tour of the locker room.

Inside the facility are several pieces of art to view as well.

Other AT&T Stadium events include college football games and concerts.

Next up was a visit to the Sixth Floor Museum at Dealey Plaza at the intersection of Elm and Houston streets in Dallas.

For $16 per person, visitors view a detailed history in photography and words of the life, times, death and legacy of John F. Kennedy. A useful audio tape with headphones enhances the experience.

The museum is located at the spot Lee Harvey Oswald shot and killed President Kennedy on Nov. 22, 1963.

Photography was not permitted here, but was one floor above, where I took a photo of the view Oswald had.

A visit to Grapevine would not be complete without trying a pair of the many wineries on Main Street.

Texas is the fifth largest wine-producing state in the United States, with Grapevine a trendsetter in the state's wine industry.

The first stop was at the Messina Hof, home to 40 different wines, tastings, premium flights and gourmet foods.

Matt and Jess joined Sally and myself. We sat outside and enjoyed tasting five different wines for only $10 per person. A semi-dry Gewurztradminer along with a Sparkling Almond and Orange Muscat Mistella dessert wine were among my favorites.

Sally and I also tried Sloan and Williams Winery and Tasting Room just a few blocks from Messina Hof on Main Street.

We tasted four different wines for $12 per person. My favorites were the 2015 Spectrum, a sweet white wine, and a 2016 Triplicity, a red wine with a bouquet of red licorice and black cherry cola.

We included a Signature Sharable Platter for $15, which included old-world meats, aged cheeses, seasonal fruits, crackers, hummus and fruit spreads.
