...6 confirmed attendees, bringing 2 additional guests. Nobody showed. Had a nice 4 hour practice session down in my (still unfinished) 30'x60' storage building - nice reverb-ey acoustics in there. Just farting around, recorded this little Be Bop Deluxe ditty on my cell phone. Seems phone audio recording has gotten way better... Anyway, it was a legendary concert for the crickets. Had a nice Monarch butterfly come and listen for most of it.
If you expect the worst from people, they will rarely disappoint you. Sorry your get together didn't work out. At least you tried.

Do it again - first meetups tend to be a small gathering at best, one at worst. It's definitely not uncommon. Sweeten the pot by posting pictures of the practice space you have, as well as any house gear. Message the attendees, get to know them. You could (probably should) do a meet and greet beforehand outside of the space, which will give you a litmus test of what's to come if anyone shows. Good luck!
