The recent contest to name the new seven wonders of the world got us thinking about our own little world here in Maryland. We must have some sights that we view with wonder. Places that deserve to be on a list just like India's Taj Mahal, Peru's Machu Picchu and Rome's Colosseum. Surely, Travel section readers can come up with seven man-made wonders of Maryland. E-mail nominations to travel@baltsun.com or mail your suggestions to Michelle Deal-Zimmerman, Travel editor, The Sun, 501 N. Calvert St., Baltimore 21278. Deadline is Aug. 17.
