As it turns out, the rain was just too heavy. We couldn't keep the sand dry, and it was clumping. It flowed, but when it sticks like that you end up wasting a lot of it, so we decided to wrap up early. Norbu went home to rest before work tonight, and I stayed to do tsog. The good news is KT jumped in to order more sand, so one obstacle to getting finished has been removed! It will be delivered tomorrow, so now all we need to do is hope a team forms to work with it! I work all weekend, so we'll see what happens. : )
