bb: Probably walkways on both levels which could work with System X.
Wes: Trying the small one on top of the large one is definitely a possibility. I decided not to get the extension floor for the large school because I wanted to do something different from the way I build my housed up and not out.
The gym should be somewhere on the ground, so a walkway would be a good way to join it, and I could always use a floor to form the roof of the walkway.
Wes,
My niece in Edmonton has two sons, a newborn and a 2 year old. Any ideas where she should shop for PM there? They will need 123 for a few years. I'd like to send her money for PM for their next birthdays. Shipping is too expensive to send actual sets. Cheers, Pgal
