I'm at or was at GO fest. Here is my post from the GO topic.
Here is my status update:
My family decided to make a Chicago weekend of this while thing. With my 6 year old and I going to GO fest.
My son and I went down my phone is on ATT couldn't log in couldn't check in.
We went back to the hotel, my wife is on T-mobile so I took her phone, went back checked in, tried to do a raid errors. I walked around hit some of the special pokestops. The special 2K eggs are apparently just any Pokémon inside. I caught a heracross. The park is an Abra nest so I had something to use my pinapps and ultra balls that I stocked up on leading up to GO fest.
Constant network errors and app crashes. Each lounge is a gym and has a special corresponding gym badge. I couldn't spin the instinct and mystic gyms because of the errors.
I headed out and saw a unown on the radar went and got it. I headed back to the hotel caught 5 more unown on the way back.
I just did a quilqva raid with 20 people we're desperate.
