I'm not sure if mmorpg reported on it, but the event is currently live.
Although I've played the game on and off for 2 years (as my 2 year gift tells me), I've never taken part in the event before.
What I like about it, similar to most of LOTRO's events, is that it's not really about grind if all you want is a nice mount and maybe an outfit or two. I got the goat mount by just doing the events once and attending a couple of firework displays (which are quite fun). Of course you can get loads more if you do want to grind, but compared to most games, I think they do this stuff really well.
I assume the goat's new since it's the most expensive (40 tokens), and that's all the more impressive that it's basically no grind to get it, regardless of whether you're a free player or not.
