Here in Utah it is very common for local businesses to be closed on the sabbath and there is strong cultural pressure among Mormons to not work or do anything that would cause someone to have to work on Sunday (e.g., shopping and going out to eat, though some take it even further by abstaining from things like online shopping or even watching television).

I don't see us headed in that direction though. It's it's becoming more and more common for businesses which had long been closed on Sunday to cave and begin opening on Sunday (it seems like it often coincides with when the children of a business owner take over). With the share of practicing Mormons in the state less than half (and falling) there is just too much missed opportunity.

Also, my own impression is that the younger generation of practicing Mormons don't seem to follow the older generations sabbath restrictions nearly as strictly. My siblings and Mormon friends almost all seem to not keep the sabbath quite as holy as our parents did.

I do wonder though if I would have spent nearly as much time as a kid dinking around on the computer and learning what became my career if my parents had let me play with friends on Sunday.
