Congrats Nero & Viper! (one late and the other in advance; seems like the girl can never be on time <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" /> <img src="/ubbthreads/images/graemlins/rolleyes.gif" alt="" /> )
Viper, I don't know what kind of woman your wife is (same for you) but maybe a session of an extreme/unusual activity could be a great idea; it would make the day even more unforgettable. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
I don't know about where you live, but here things like a parachute drop, a rafting raid or a delta wing/"montgolfière" (air-balloon?) tour are affordable enough to be offered as gifts. And for a wedding anniversary, it can be pretty symbolic too. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
