Forgot to mention in my email of a moment ago:   David at UT asked what type of tree we had in mind to plant.  I suggested a native sapling (dogwood?redbud? conifer?--you probably have more knowledge about this) that would be larger than a seedling, and thus a bit more substantial for media purposes.  I have not priced trees at a nursery, but assume that we would cover this cost.  I can help with this if need be. 

Thanks,
