My new favorite shop is Park + Vine. It's a boutique that opened in the Gateway Quarter of Over the Rhine. They carry green products: backpacks with solar panels for charging your portable electronics, bamboo table accessories, vinyl records reshaped into bowls, etc. They also carry izze soft drinks and energy bars in case you need a tasty beverage/snack while shopping.
Urban Gardening is also a brand new shop in the Gateway Quarter. The shop owner was very nice and they just opened today for the OTR Summer Tour of Homes, so things were a little disheveled and the water feature in the back didn't have any water in it yet. They featured self contained herb gardens and starter plants for pocket gardens.
The OTR Summer Tour of Homes seemed pretty well attended for a first time program. The Duveneck Lofts were super nice and Penthouse 3 unit in the American Building would totally be worth the $1,050,000 if I had it.
