WATERLOO, ON Contact: Jenn (hi@jenn.site) Date: May 15 Time: 1:00 PM Coordinates: https://plus.codes/86MXFF7H+F3F Location: At the benches lining the south of Waterloo Public Square. I'll be wearing white doc martens and carrying an "ACX" meetup sign. From the square we can decide where to have lunch :) Notes: If it's rainy, we'll meet under the covered entrance to the Starbucks at 95 King St S instead. Not inside - the shaded area where the outdoor tables are. Group info: I used to host regular SSC meetups but have since lost the energy needed to sustain that. However, I'd be interested in trying to restart with a co-host if anyone else is interested.
