I actually had a pretty good Community Weekend! It's certainly the most active I've been in the game in quite some time.
My husband came out with me and we went to the Vondelpark (huge park in downtown Amsterdam) for the first day of the community event, spending the full 3h walking there and inside there, aside from a short stint to walk to a grocery story to grab lunch. I caught 6 shiny Eevee that day, which would have been enough for one of each... except that my first 4 evolutions were two each of Flareon and Vaporeon.
As such, I needed to go out today as well, and my luck was at least faster. I caught a shiny right in my house as soon as the event started. I evolved him right away and got a Jolteon, so I was technically set, but I wanted at least one more to keep as an Eevee, too. Husband and I just kinda wandered around the city for a couple hours and I caught 3 more shinies, enough to keep one Eevee and also save two for Glaceon and Leafeon, presuming Gen 4 will be coming out at some point.
