The small single location bank my parents used and started my first savings account at got bought by a slightly larger local bank, which over the last 30 years has grown into a reasonably sized regional bank covering 2/3 of Illinois and 1/4 of Indiana. Seems to be a really good size as they're big enough to offer the services of bigger banks like an excellent website and atm's everywhere, but small enough to still have my local branch where I know all the employees by name (went to school with a couple of them) and they know me.
