Our anniversary is coming. I need ideas!

Iím running out of ideas as to how to surprise my girlfriend on the day of our anniversary. My girlfriend used to put up a lot of effort in surprising me. Sheís very sweet. She doesnít mind being the one who takes effort in surprising me though sheís a lady. Donít get me wrong. I do surprise her too but she does most of the time. Sheís fond of surprises, thatís why. This time, I want to do the same thing for her. I want to make it up for her. I want to see her happy. But how? I want a unique surprise but I donít have any idea of what I should do. How about Ukraine ski trip? Will that be romantic? Iím confused as to what to do now. Can you help me out with this? I badly need suggestions.
