Intellectual stimulation (or lack thereof)

I've been feeling the isolation of being in a place NOT the same as the university that will grant me my degree when all is said and done.

I knew it would be a tradeoff coming here - that work, life, kids education etc. would be easier, but writing the dissertation would be harder. But it's felt particularly poignant over the last few days because:
a) I received email notice about a workshop that I'd badly love to attend but can't since it's 3000 miles away
b) A friend and colleague is defending and I won't be there for it.
c) I'm realizing that with the end of the semester (for most people) that everyone is busy and I should not expect responses to the various queries I have sent over the last few weeks.

I've tried to alleviate some of the isolation by attending events at the local university, but with the term winding down, those will also dry up over the summer. We did go to the local sciencecafe last month, and I hope to go again this month, but that's only one evening every four weeks or so, and doesn't really satisfy in the way that attending a lecture or defense would.

I'm taking summer off from one of my jobs, so I'll have more time for writing, but with the summer also come even fewer opportunities for intellectual stimulation. At least the internet is a (poor) substitute, that will hopefully keep me going till I get through the writing!
