I've been to fish club meets in a few places over the years. Some just for an occasional talk or big auction. I don't stay up late anymore, so night meets have to be of big interest to me or if my carpool friend drives.
Now I belong to an aquatic plant club but haven't been in over a year. It used to be more fun when we met for potluck lunch, often at a member's home, lfs or park. We use our real names before you can join. We don't really have a club organizer but try to have them in different areas of our large metro region. We always have a free "pass the bags of plants", sometimes people sell, trade or give away fish or equipment. Covid killed the home meets & potluck

It's just not the same. I twice had meets at my house to help set up new tanks. People brought food, plants & hard scape & as host I got first pick, lol. Some of the members are planting & scaping machines! They took a couple hours to do what would have taken me at least days or weeks. I always try to talk to new people about their tanks & offer my low-tech limited help with plants that might work for them.
I used to think of myself as fairly shy, but I guess not really in some ways. I've tried to be careful of people, especially kids I've "met" online. Meet with parent in lfs parking lot, etc. But also suggested going a local club for a meet or 2. Once my husband & I were walking around a nearby reservoir & brought back a biggish log. A guy said "I hope that's going in a fish tank", lol, so of course we stopped to chat. I've also tried to include family & friends in my hobby whether through gift tanks or plants

@GaryE, I think I've been to that CT meet a couple times, lol.
