Many of you might remember that a while back, we organized a Stormwind Stampede, where a bunch of us created a herd of Tauren over on Zangarmarsh, and then had a little footrace all the way to Stormwind. Our friend BigRedKitty is apparently putting something similar together this weekend -- he's calling it the Cinco de Mayo Running of da Bulls, and the final goal appears to be from Mulgore to Hammerfall (which means there's an Org to Undercity zepplin ride in there somewhere).
The whole event kicks off this Saturday, May 3rd over on Cenarion Circle. BRK is organizing the thing along with Ratshag of Need More Rage (he's the one who created the route, and it'll be his friend you're hunting for in Hammerfall). He's got more on his blog, including that the race is a tribute to a friend of theirs who passed away, and all the Tauren will be saying "moo" in respect.
Sounds like a lot of fun. If you want to join them, meet up in Mulgore on Cenarion Circle at 4:00 server time (which works out to 7:00 Eastern). And make sure to take some screenshots. For the Herd!
