Don't lug Masonite along unless you have a brand you really can't live without.

A local hardware store has 1/8" and 1/4" masonite and it's fine and cheap. Likewise, there are reasonably-priced painting and drawing supplies in town in student-to-mid grades. If you're a professional and use high-end materials, by all means bring them, but you can get adequate stuff here for most of what you'd need.
I live in town, and if anybody wants to just ship stuff to my home, I'll be happy to bring it down on the first day.
Thanks for the info Steve! I'll probably wait until i get there for the masonite, and just make sure that i can get it home on the plane (in my suitcase, as Jen did last year, or possibly in a separate package). And i may well take you up on getting some materials shipped to your home!
And Mark, thanks for the info on the board. As far as I can work out, MDF is much more common in our hardware stores. So i'll probably get some masonite in Amherst for the workshop, and the try out MDF over here.
Corina, i think i'm going to try and keep my supplies to a flexible minimum. Hopefully, if i get some practice in before June, i'll have a better idea of what i can and can't live without!
And thanks for the link, Madeline! That looks like another option for getting some paints and mediums when i'm over there.
