This is actually a Harvestman spider. Commonly called Daddy Long-legs because, well, you know.
This one is a female. You can tell the gender of most spiders by looking at the size of their pedipalps, which appear to be legs number 9 and 10 and are found near or just below their pie hole.
Slender pedipalps indicate a female spider, whereas fat, bulbous pedipalps indicate a male.
These spiders are quite common up around the Susquehanna River area of Northern Maryland. Several of them crawled up onto me as I laid on the ground shooting their cousins, or some other creature.
It kinda gave me the willies.
