What do you do with your pack after you've arrived?

Hi all,
I've been training for my camino by walking to and from work every day, which is 6 miles each way, and even with this short distance all I want to do when I get to where I'm going is put my pack down and leave it down. Because of this, I've started wondering what the general practice is when exploring the town/city, after checking in to an albergue and probably cleaning up a bit.
Is it safe to leave the pack in the albergue (while taking things like money/passport/camera with me), or do I have to lug it around some more? While my first thought is "hey - we'll all be pilgrims - it should be safe to leave it", I am also not quite that naive as to the ways of the world in general.

What have you pilgrims of the past done??

Thanks for the quick replies!
I'm so glad to hear that everyone leaves their packs behind!! Not only because it means not carrying it more than absolutely necessary, but also because of the volumes it speaks to the general atmosphere and sense of community. This ability to trust those around me makes me even more excited about this journey - something I wasn't sure was even possible!
And yes - while I'd be a little upset at the fact that the months of saving to be able to buy the supplies necessary would be for naught should my pack be stolen, so long as I still have my identification I know I'm set for whatever comes my way. I would like to come home with all the supplies I took with me (as I'm really focusing on not taking more than absolute essentials), but if a curve ball is thrown my way, so be it. I could probably afford to be less materially reliant anyway.

Thanks again.

PS - I hope I get a chance to meet some of you this summer! Anyone going during the peak times (June 29-July 25)??
