This afternoon Maya, her friend Lydia, and I made further progress on her treehouse. Maya and Lydia pre-drilled all the anchor holes in the flooring after I showed them how to use the drill. The floor deck and supports for the roof are completed and ready to be hoisted into the tree (perhaps next weekend, weather permitting). We will add the deck boards, railings and roof, after the frame is in the tree to reduce the weight we have to lift.
