Real Estate Investor Clubs

Fairly new to investing. Have 1 rental for 6+ years. I wish to expand now to more but want to learn more.

Are real estate clubs worth joining? What should I look for? Clubs in my area are very few. (Richmond, VA) One club I am looking at looks like its run out of someones house. Is that normal? Are some of these clubs full of loan sharks? Just tryin to avoid scams ya know.

Thanks
