My question is this - is it possible to 'tag along' to such meet ups
and if so, how do I find where and when they are?

http://skyandtelescope.com/resources/organizations/ will find
clubs near you. And yes, public nights in particular are for
people to tag along. And every club will have some people who
enjoy helping others get started.
