Have you been to the National Arboretum in NE Washington, DC? 10 minutes from the capitol. We were just there three weeks ago. An amazing collection of many bonsai, penjing, suiseki. When we were there, there was a juried show of ikebana.

The extrordinary bonsai (several are gifts from heads of state from their personal collections) are in a series of pavillions and gardens, including a Japanese stroll garden, a walled Chinese garden, a Chinese scholar's room and an exhibition hall and open-air display areas for the bonsai.

Have a wonderful trip!

If you get to New Jersey, a visit to Allshapes Bonsai Nursery would be nice. They have a selection of established older bonsai and many pre-bonsai for purchase. Check their site for directions & hours.
