My wife and I starting playing WoW at the same time back in Vanilla. We were in our mid 20's when a mutual friend that had a level 60 Hunter ran us from Gadget all the way to Cenarion Hold in Silithus. There are two moments that are seared into my mind from that journey.
1. Devilsaur - I couldn't believe it, it scared me shitless, especially with my friend typing "RUN!!!! RUN!!!!!!!!" in party chat lol.
2. Those tall hives in Silithus that you can see from the road. I wondered what incredible journeys I would eventually be going on in this game.
