Last year my boyfriend for a camera bag with a memory card on the beach in the Boston area. Find owner?

He found this memory card with pictures from Las Vegas, the Grand Canyon, Hoover Dam etc. There are also 2 pictures of what we ume is their backyard with several pumpkins in the gr. The pictures were taken in October 2006. There is also a picture of a couple having dinner in Las Vegas with the Paris in the background. We ume that they are the owners of the card. Anybody have any good ideas of how to find them? We wold really like to return the card to them!
