Hi. There are three boxes at the Arboretum if you plan to go there.
E-mail me off list and I can give you some clues on how to get them
without backtracking and walking your legs off. The box clues
themselves start from different points on the grounds but you could
make a walking loop out of it to get all three.

Of course, you could probably just pick up a map of the grounds and
figure it out yourself. ;-)

Also there is a fee of $6 to get into the Arboretum unless you go on
Tuesday, when it's free.
