I know I've mentioned this before, but if you are in the area and haven't checked out Glencairn castle in Bryn Athyn, you really should try to get down there. It is quite an experience to see a medieval style castle, built using tradition methods and housing so many ancient artifacts so close to home.
We went down today for their home school days, which are always great because of the special pricing to get in and the great tours. Since it was raining, Christian was able to take off work and head down with us. Yay!
