I count myself really lucky to have met a great guy through WoW. I hear it happens more than one might imagine, and I can only assume that that's because everyone who plays WoW is wonderful. I will not hear of your evidence to the contrary, so zip it.
When my sweetheart and I first started chatting in-game, a lot of the time it was PvP-related, and we used to duel on the top of the highest hill in the Stormwind area. It was the only place I even had a chance of winning at the time, seeing as I was a protection paladin with zero resilience and he was an experienced affliction warlock. Let's not discuss my dubious early PvP choices now, though.
That hill kind of became a special place by association, the place I'd go whenever I was idly wandering or just chatting rather than doing anything useful. It's got a great view and a lot of happy memories associated with it. So it made sense to me to get a Romantic Picnic Basket and Have Group Will Travel him up there on Valentine's.
Do you have a special place in WoW? It doesn't have to be for romantic reasons, of course -- it could be for anything. Why is it special to you? How did you find it? What do you do there and why?
