This morning my blog dashboard says I’ve published 2,400 articles.  Such a lot of writing!

In honor of that feat — and because I’m on vacation — I’m taking a one-day break and directing you to two vintage posts you’ll find of interest:

• What’s that vine that blankets Pittsburgh’s hillsides and overgrows our parks?  It has a pretty porcelain berry.
• How do some birders know in advance that there will be good birds on a September morning?  We watch fall migration on radar.
