I feel good most Sundays at church, but that's largely because I have tried hard to develop a true love for other people. I "feel the spirit" regularly, but I'm not sure exactly what that means, really. Perhaps I just feel the "warm fuzzies" more naturally than some.
As far as where someone can feel the spirit, I believe that different people feel God's love for them (solely or more intensively) in different situations and different places. For Joseph as a youth, it was a grove of trees; for Enos, it was while hunting, surrounded by God's creation; for some people, it is at church among their believing peers.
I go to church to be and worship with others I have CHOSEN to love, no matter our differences - so I tend to feel good while I'm there regardless of what's being said in talks and lessons. When I am edified by a talk or lesson, which happens quite regularly given my attitude toward them, great! When I'm not (and even when I cringe or disagree), great! I'm still with people I've chosen to love in a setting I've chosen for myself.
It's all good, even when it's not all good - and that is important to me.
Oh, and the sacrament hasn't been accompanied with an outpouring of the spirit for me in a long, long time - if ever. It's something important I do as a token of my remembrance of him and commitment to live a Christ-centered life - not as a vehicle to feel the spirit. It just doesn't work that way for ME.
