Love your image of the Secret Garden in Portland, and would really want to see it for myself when we travel to Portland in July. But when I try a Google search for Secret Garden it brings up 3 separate locations in the Portland area - Crystal Springs, Bishop's Close/Elk Rock, Leach Botqnical Gareen. Need to know which of the three gardens has this beautiful view of the tunnel like trees. Any help you can provide would be appreciated.
After some digging as that pic was posted over a year ago, I think I found the pic you are wondering about. I did not take the pic, the link below and subsequence click through leads off site and lists a name of architect 41 .
Follow the link and they should be able to help. :)
Also in the future a link to the pic in question would save me a bit of digging time. ☺
