You may park anywhere on the street you like. Free parking. If you prefer to find the church parking lot, you may find that entrance off of Rubel Avenue.
For reception parking, Patrick O'Shea's Pub recommends the 1st and Main Parking Garage located at 100 E Main Street. There will be a fee to park, but we go on and recommend biting the bullet for good parking. It will be hard to find decent free parking in this area.
