Thanks, tomc -- great reminder!
I want to go to a small arboretum run by a retirement community in the neighborhood to see what kind of native oak trees they have and collect acorns (advantage of going to an arboretum is that each tree will be labeled

)
I meant to do that last year but missed the opportunity. When I called, they did tell me that the oak tree species drop acorns at different times throughout autumn, so several repeat visits are indicated.
