It wasn't completely internet-free, because there was wifi at my Mom's place and wifi at McDonald's for the occasional stops and wifi at the very nice Dead River Cafe in Marquette. But for the most part the net was kept at bay, since T-Mobile data service ended at Pinconning and I was with a phone that didn't have internet-everywhere coverage for the better part of a week.
There are a couple of places I would have liked to have captured in the moment while I was there with a camera and with Twitter to share them. For example, there's the cutest little gazebo-like structure on the Iron Ore Heritage Trail underneath the LS&I railroad trestle. It's cute until you realize that it's there to deflect the ore pellets off the trail and off of the heads of passing bicyclists as they go under an active set of tracks.
I also missed there being a local wiki to look things up in (and to add my own commentary to) for the Upper Peninsula, along the lines of Ann Arbor's Arborwiki. There's a lot of history in the area that's still relatively unwritten, and it would have been fantastic to have a place to store bits of commentary and observations without necessarily broadcasting a stream of social media to my long-suffering friends.
I'm back, not having missed Facebook much at all, and not having been tethered to a Twitter update stream, and only 100 messages behind in my inbox.
