S., If you are out in town, there are activities at Luckie Park or at the other parks and Recs, you might check into. If you are on base, The ASYMCA has programs for the military children of pre-school age. There are play groups and etc.. Look around at the community centers and such.
A bicycle with a trailer might be a great option,to get you around....pack a snuggly blanket,a favorite toy, a snack and a sippie cup, crayons, paper, or sidewalk chalk is good, or if you are staying inside, go on websites and shop for crafts from places like Highlights.com. You can even do printouts from Nickjr. com, Disney, etc...
OR since your son is almost two, you might get him interested in computers early, and sit with him while you surf the net for kid stuff, many sites have games,puzzles and etc... teach that little guy how to use a mouse and he'll be ahead of the game when preschool comes up. Good luck!
