i love being on the other side and watching these students learn new concepts and ask questions. we want them around a long time. note that there is no built-in bathroom but you can rent a portable camping toilet for just $10 extra. how high do you have to go for the water balloon to break on the pavement? starting with the easy questions will probably put you ahead of the clock. it was like watching our home and family from our son's perspective which was very moving and sweet. i, for one, will be sad to see these things go.
