A faint trail, artfully concealed by bushes and trees planted in such a way to obscure theits departure from the bridle path, leads to an arched oriental bridge over a slowly flowing stream. When viewed from the side, the bridge and its reflection in the water create a perfect circle.

Depending upon the time of day and time of year, fog may partially or wholly obstruct the view of the bridge. 

The bridge crosses north over the stream. The trail extends to the south. Which path will you choose?
