We aren't scheduled to do a series in the Fall; perhaps Spring, 2018, will be my next series. My other five topics are Eastern Europe, Western Europe, Latin America, the Caribbean, and Canada/Alaska.
If you don't know OLLI, it stands for Osher Lifelong Learning Institute. Its purpose is to organize and offer enrichment/edutainment courses for seniors at a quite modest price.
OLLI chapters are normally associated with a university or college campus, although the courses they offer are much less formal than college courses - no tests, no grades, no credit, attendance optional, show up if you enjoy it.
To find if there is an OLLI chapter near you, check out their list of locations at:
