It measured around 4 inches from the tip of the front legs to the end of the rear legs. It was on a wooden bench in a shady woodland area. After looking closer at the photo I realized the spider (?) only had 7 legs! Maybe it lost one leg to a predator.
Not a true spider, but a relative in the order Opiliones. They commonly are known as harvestmen or daddy long-legs; these all are harmless. They often lose legs through a process called autotomy - http://www.americanarachnology.org/joa_free/joa_v26_n3/joa_v26_p296.pdf
Thank you Flapdoodle! It matches descriptions of Harvestman - Leiobunum vittatum?
That may well be a possibility, but there are very few species of harvestmen that I would be willing to tag specifically based just on an image.
