What a wonderful opportunity! Do consider Washington, D.C. We usually stay
in Virginia and take the metro into the city. There are events at the Mall
all summer and the museums are great resources and mostly free. You can
photograph most of the artwork in the National Gallery (without flash) and the photos
can be a great resource. I had a photo made of myself next to Leonardo's
Geneva d'Este because I use it in one of my lessons. My kids were facinated by
the "real" painting and it gave them a better understanding than just telling
them about it.
The Boston Museum of Fine Arts (oldest in the US) is worth the trip in itself
and as someone mentioned there are lots of other great things there .
Charleston, SC is a wonderful place too. Our state conference will be there in
October, but my favorite time to go there is the South Eastern Wildlife Expo in
February. The whole town is devoted to wildlife art and artists. Art shows
draw top professional artists from all over the world. Spoleto is the major art
festival there, which is mostly preforming arts and music, but also with a
full range of attractions. That being said, my favorite city in the US to visit
is Seattle. The other places are great for seeing art, but Seattle makes me
want to create art.
