Well, I opted for walking during the kids' activity, it was too cold to loiter at a Pokestop for half an hour.
I got three buddy candies and hatched a 10k egg. The kids are extremely jealous as my egg gave me a 1664CP Lapras! And the hatching, along with the catching and transferring on the walk, took me up to a Level 21. Not bad considering this coming Thursday it will only be three weeks since I started playing. LOL!
That probably explains why I'm now sick of the sight of Gastly, Haunter, Meowth, Drowsee and Hypno despite barely seeing them before the event, this event has been almost half of my total playing time so far. :)
