Dawn, Not sure where you live but Louisiana has Parishes, not counties like all other states. East Ascension is Ascension Parish but described as "East Ascension" because it is on the East side of the Mississippi River. The main city on the East Ascension side is Gonzales, LA. Between Gonzales and Baton Rouge is an area called Prairieville.
