Note: the best way to enter Richmond Green right now is from the Leslie Street entrance at the first lights north of Elgin Mills (the main entrance on Elgin Mills is a vaccine clinic entrance)
This is a straightforward, two-stage multi within Richmond Green. Your first container will have coordinates in it for the final that can be found a short walk away. If you have more time--or children with you--there are playgrounds and other amenities within the Green too.
Both containers for this multi match the size indicated in the cache listing.
Congratulations to SCRedstone on their first First-to-Find!
