There is a space for indicating your "Location" and "Dojo" in your profile. I see you've entered your own location. If others wish to have such information publically available, they'll undoubtedly include that information in their profile (and also below their name in every post they make).
As far as events in your area, you can take a look at seminars by state in the United States in the seminars
section of this website.
Also, if you are looking for a particular dojo in a region of the United States, the dojo search engine
on this site will allow you to, say, list all dojo within 50 miles of Portland, Oregon. You might want to try that out.
Hope that helps,
