My mid-sized PVE server where Horde is a big minority get's CRZ'd with Area52 and several other huge servers. Finally I made a macro "/tar snowy owl" and started picking random Shat daily groups. Found one in about 20min of doing that after flying around the zone for 2 hours with at least 100 other people.
Finally got mine today, took a couple hours of just searching for it. I am on a smaller server so I had to kill quite a few pets to bring in fresh numbers. It's out there so don't lose heart as I almost did. Now I have my new owl rare-stoned and 25 and I love her already!
I still need to collect one, but I am unable to spent the time required until (maybe) Sunday. I tried quite a few hours last year with no luck. But I did succeed in finding an Unborn earlier this year, so hopefully the Snowy Owl will appear to me. and I just figured out which non-90 or more ladies to use.
The bad thing about the Owl showing up now is that I simply have too many Holiday obligations to finish first.
