For traveling seniors who want to recall childhood days of enjoying their miniature railroads, this is the place to go.

The San Diego Model Railroad Museum is located in Balboa Park, on the lower floors of the Casa de Balboa. Celebrating its 100th birthday, the building was featured in the 1915 Pan Pacific celebration. That year, San Diego joined other cities marking the opening of the Panama Canal. The Model Railroad Museum was created in 1982.

Basically, all you need is to show an outgoing personality, courtesy and conversation skills. You can do it alone, but it’s easier for two guys or two gals together to blend in. As a pair, you can successfully meet with other couples or groups on cruises, excursions or other places where seniors gather to gab, ogle, mix and match.

At social gatherings, make sure you don't stand in a corner waiting for something to happen. As politicians always do, work the room. Introduce yourself, start conversations, tell jokes, sing a stanza from a popular song and let everyone know you're the most interesting person there.

Familiarity with the city can give visiting joggers, bikers and hikers many choices of routes to follow. Check with your hotel front desk for the best on the day you  plan to go. The safest times are from sun-up to 8 am, and from 6 pm to sundown.

For instance, start at the National Mall, where you can cover the two miles around the perimeter from the Capitol steps to the Lincoln Memorial. Or venture into the Reflecting Pool area. If you want to mix your exercise with some activities, where there are often interesting events there, such as lectures, concerts and group exercise classes. If you happen to be there during Cherry Blossom time, you'll really be in the pink.

You can jog past Dupont Circle and up Embassy Row from Massachusetts Avenue. It gives you the opportunity to observe the stately lines of elegant buildings, and imagine all the political intrigue and posh social events going on behind the fences.

On permanent display at the popular tourist attraction, the Ford Model A also displays the price of gas as it was way back when.
