Yahoo! Picks - bringing you the best of the Web since 1995

Does grocery shopping feel like just another chore? Maybe that's because today's big-box retailers and discounts stores have lost the kitschy charm of 1950s architecture and sleek 1960s modern styling.

If you miss the pre-prefab Safeways or perhaps you're lucky enough to have a vintage Luckys down the block, you may want to join David Gwynn and the legion of "groceteria" fans who swap photos and stories about charming Winn-Dixies and A&P markets.

Gwynn's site combines well-researched history with a dash of nostalgia, a small dose of irony, and a lot of love for the days before cookie-cutter strip malls overtook America. We caught up with David in between shopping trips to see what's new in the land of old stores.

Everything is a lot cheaper. And the lines are a lot shorter. And here, we have liver pudding and Cheerwine freely available in all stores.

Every other year, World Monuments Watch makes a list of the 100 most endangered sites in the world. In compiling the roster, experts consider the significance of each site, the urgency of the threat to it, and the viability of a solution. Many of these places have been designated UNESCO World Heritage Sites, but that doesn't protect them from erosion, abandonment, development, weather damage, or from being loved too much—by tourists. Spin the globe and learn about our endangered cultural heritage. Start with these seven wonders and the causes that threaten to wipe them from our map.

• Giant stone Buddhas in Bamiyan, Afghanistan—erosion, human destruction
• Missions of Chihuahua, Mexico—abandonment, exposure to the elements
• Rock art of Dampier, Australia—industrial development
• Machu Picchu in the Urubamba Valley, Peru—development pressure, unchecked tourism
• Historic neighborhoods of New Orleans, United States—hurricane damage, limited resources
• Farnese Nymphaneum in Rome, Italy—biological attack, rain and flood damage
• Historic sites of Kilwa, Tanzania—rising sea, coastal erosion
