I spent part of my weekend finally visiting Blue Hill at Stone Barns in Pocantico Hills, NY. The farm is just 50 minutes outside the city (without traffic ie. never actually 50 minutes), but well worth the trip.   (You can also take the Metro North!) The property is gigantic -- full of greenery, livestock and rolling hills.  It's absolutely beautiful and especially breathtaking when you realize your normal view is often the complete opposite.  Luckily, guests are allowed to take self-guided tours, so you can spend the afternoon getting lost in the terrain.  We visited lots of farm animals (my favorite part) and spent way too much money on overpriced weck jars and organic linens in the beautiful gift shop.  The restaurant, located on the property, offers an eight or twelve course "farmer's feast" with no menus, only true farm-to-table food.   Instead, we opted for a quick snack at the Blue Hill Cafe, which features farm-fresh salads, snacks, coffee, etc.  Although we only spent 2-3 hours there, it was wonderfully refreshing and I recommend anyone visit if they haven't already.  Just be prepared for the depression you'll feel after arriving back in the city sans sheep and pigs.
