Sipsey should definitely be in the dictionary of wordnik.com. Sipsey is a National park in Northwestern Alabama. Sipsey is the largest national forest wilderness area east of the Mississippi. A beautiful place to visit. Hiking, horseback riding, fishing, camping, and hunting are allowed (and no, I am not affiliated in any way, shape, or form with the National park). Definitely a word to be in a dictionary, I believe, but I could be wrong.
