What to bring to an office potluck???

I have been trying to decide for a week what to bring for my Division's Potluck Lunch at work tomorrow.  It has to be something that travels well since I have quite a walk, in snow and ice, from the parking lot.  At a past event, I brought in a hearty crock pot soup.  But even in a zippered case with the lid supposedly clamped in place, it was kind of a mess!  Actually, not "kind of a mess", but "a mess!"

Finally, this morning I sat down with one of my Southern Living cookbooks, idly turning the pages to find inspiration.  Ahhh!  That's it!  Hummingbird Cake!  I've never made one but many people over the years have told me it is a real winner.

The list of ingredients would charm anyone:  crushed pineapple, mashed bananas, cinnamon, chopped nuts and a cream cheese frosting!

I want to put in a good word for the Southern Living cookbooks.  I have several of them and every recipe is a sure winner every time.
