I voted old school cause that's what I believe in.
In reality I happened to make an off hand comment to her "maybe we'll get married" about 3-4 in the morning while at our "closer" watering hole and by 2 pm the next day she'd already set a date and had the hall booked even though we did not roll out of bed till 1 so I just went with it.
Married 16 years, together nearly 20.
