I spent most of my childhood in a peach tree. So today at the Dallas Arboretum, I did a major rewind — as in color me 8-years-old — when judging plans for treehouses from 54 local architects. The Arboretum, which gets smarter at marketing every year, gave any interested architect his/her choice of 12 trees, and each entrant designed for the chosen tree. The plans were genius. You will be able to see the winners in mid-June. That is, you and the 120,000 visitors who are expected to attend the exhibition. Don’t miss it.
