Here's an interesting superstition. It's supposed to be bad luck for children (or anyone else) to climb trees on the Friday before Easter. Anyone else ever hear of this?
Then here's to the oak, the brave old oak,
Who stands in his pride alone!
And still flourish he, a hale green tree,
When a hundred years are gone!
--Henry Fothergill Chorley, "The Brave Old Oak"
