A plus is a local market to get ice
and film (and whatever you've forgotten to bring). although it is a bit pricey.
A hint for smooth sailing: treat the
staff like gold. Thank them often, give them clay goodies and show them what
you're doing. Give them a piece of clay to play with and get them hooked. Be
prepared for snafus and be kind to those who are working hard to smooth them out
for you.
Now you go to the retreat packed with
everything you'd take to a Clay Day, meet new people, learn new things, eat too
much junk food and stay up past your bedtime.
