It's time again to celebrate a city besotted with gardening -- Buffalo, which hosts its annual Garden Walk this weekend. 370+ city households will throw open their front and back yards to thousands of visitors, who tour self-guided through neighborhoods tony and raggedy -- some of them revived in large part by gardening that's spread like a good virus block-by-block. Lots of intense small urban spaces and often low-budget creativity. My earlier paean here; albums here; update on the spreading fame and impact on the city in the Buffalo News here; info on the self-guided tours, maps, etc. etc. here.
