I realize that visiting a church may not be one of your "must see" things to do in SL, but I have been known to slip into one. I also have an couple of SL friends who attend services on a regular basis.
So the other night one of my SL friends mentioned to me that a relative was in the hospital. I don't claim to be over religious, but I do keep my connection with God open. Something led me to do what I did and take that experience in-world since I was online at the time. It was easy to do a search in SL to find one that looked most inviting to my need. I love that these places are pretty much open and available to us pretty much 24/7. Here is the SLURL to the one that I took my prayer to :
