the last museum we visited was the frick collection. frick was a super wealthy guy from pa that just liked to collect incredible art from peeps like el greco, monet, van gogh, turner, degas, goya...the list goes on. he left pa for nyc (holla!) and bought a lot on 5th avenue between east 70th and east 71st. no bigs. he built his home there (or rather a bunch of construction people did) and wanted his home and collection to turn into a museum one day. and it did. and it's amazing. the building itself is beautiful and historic and huge. the art is just a bonus. a big bonus.
so, try it. you'll like it.
the only downside is there are a lot of other people that go to museums when we do. like sometimes lines form to get into the museum. ugh. but honestly, i will tolerate the crowds if it means free/cheap.
if you want more info on free/pay as you wish museum times in nyc, go here.
