No one's mentioned local groups; over here in the UK every town and even small villages have groups of enthusiasts for all kinds of activities: The Women's Institute, Historical Societies, Photography groups, Gardening clubs, Retired Teachers' groups, Rotary clubs... and many others.
Their usual practice is to meet monthly and to have a speaker, followed by refreshments, a raffle, announcements, etc. They love to have "something different" (they don't just want talks related to their own particular activity).
Do you have clubs like this in your area that you can contact? I happen to be well blessed where I live, so I get to do lots of readings - and sell lots of books.
If you do this, Jake, don't just read from your new book though. Give them a taster from it, but that's all. Read other poems you've written and fill in with anecdotes, invite the audience to speak to you about poetry; entertain them, make them love you and they will buy your books!!
That's my advice, FWIW. Good luck.
