The irony is my hometown is a couple of hours north west of Philly, were I grew up Russian Orthodox.
I moved to the Bible belt 20 years ago, and finally after leaving a methodist church down here, now go to a pretty cool technically Baptist church (way too much fire and brimstone down south for me, I don't need to told I'm going to hell LOL).
3 hours on a regular Sunday would be way to long for me. Heck, I go to church wearing shorts and sandals most of the time anyways.
However, you're with your family during this time, and don't forget that. I lost my one 16 year old boy this year, and I'd give ANYTHING to be able to spend 3 hours in church with him one more time to tell him how much he means to me
