In any case, this means a re-assessment of my next step is called for. I may re-attempt an Old-School D&D Group at the bookstore again in the future, but I need to regroup and re-prioritize a little bit first.
As I recently reported, there are a number of local game shops I have not yet set foot in. So that seems the next most likely avenue for exploration.
Especially promising in this regard is the recurring Retro Games Night at Pair-A-Dice Games. Maybe I'll just show up there on October 1 with Labyrinth Lord rules and The Lost City in hand, and see what happens.
But most immediately, my plans include getting a ConstantCon game started. I will make an "official" announcement of this soon, and will advertise the first virtual meetup on this blog and on Zak's Wednesday "bulletin board" immediately thereafter.
