We have a standing invite to set up and do "ambush astronomy" in front of a bar and liquor store with an... interesting reputation. From past experience, before sunset women show up and get their booze of choice clean cut people in business attire get their craft beer, hipster kids roll through and get whatever artisan avocado toasted ale they get. Then, when the sun goes down, it is all rough-around-the-edges blue collar and biker types. The bar has a reputation for back in the day there were stabbings, drugs, gangs, etc at the place but now it is just a bar. When we go and show up, the first rough looking chaps will wander over, go something along the lines of "NO SHIT YOU CAN SEE THAT?" and start making calls. Ernest is one of the big guys who has been there for years and when we are there, and he is there, he barks for us, in an endearingly rough sort of fashion. more along the lines of "get your punk ass over here and look at the nerd shit asshole." We have fun, we get 200+ people looking through the telescopes and we get funny stories to tell.
There are other groups that intentionally target bars for outreach which is where I got the idea. We've been invited to some of the high-brow bourbon places because of the bar nights, and the bourbon places offer donations to the society so everyone wins.
The shit I do for this fucking club, man.
