Marion,Here is one more suggestion for finding the type of venues Genie mentioned. I don't know whether your local paper has a Health page. The Washington Post has a health section every Wednesday and there are always ads for retirement homes, etc. Every three months they have a Seniors' edition with many, many ads.
For me this was helpful because I could get a "feel" for each facility from their ad and also some of them specifically mention organized activities or stated that they have an activities director.
