For me, I like writing in total silence in chunks of time. If I can't get more than an hour to myself then I will just spend it surfing blogs or posting. Usually I don't allow myself to read blogs at home much because it takes away from my writing time (knee deep in WIP) but since vacation doesn't offer much solitude, it's a guilty pleasure I dive into.
Speaking of diving (lame set-up I know) but I need to hit the pool this AM, after the gym of course. You guys have a beautiful sunny day!
Does your writing, blogging, commenting go on vacation when you do?
