Have to have Mickey Ears. I don't know yet how to upload pictures but I have a great one with my kids & their faces covered in ice cream & chocolate.
Also, when my DH & I started taking trips together, I started collecting magnets of everywhere we went. Even for the day-- trips such as museums, amusement parks, etc. I look at my fridge now after 12 yrs of marriage (together 15) & fondly remember all the things we have done together. So when we duplicate some place I try to get a magnet with a year on it.
