Here in Dallas we are lucky enough to have a gorgeous and well-maintained arboretum. A few years ago my family got a membership. I dreamed of going often, studying and writing papers with my best friend while we were in grad school. That never happened, but it was a good idea.
2 years later and my family has a membership again. In the month that we've had it, I've visited the arboretum 4 times. It's the best time of year to go- everything is in full bloom! Being surrounded by all the planty goodness outside had me craving planty goodness inside, so I brought the outdoors in.
