In a previous post, I mentioned that the church we are having the wedding at does not have very much parking. Since then, we've talked to the manager of the Dollar General store next to the church, and she will let us use the row of parking spots next to the street. This is only 12 more spaces, but it's a little bit more parking. She cautions us to not use the spaces close to the store or close to the rail tressle between the parking lot and the church parking lot, because there will be some truck traffic (trash truck and a shipment truck) loading and unloading that day.
There is also a park nearby that you may be able to park next to; the north side of the park is open to parking; however, parking is prohibited on the remaining 3 sides.
Otherwise, we would suggest trying to car pool from the hotel as much as possible or parking at the campus near the student union and car pooling to the church from there.
