I'm glad to say I'm finally out of PA and into NJ!
I enjoy the drives to the trail, but they're getting longer, so I've built in a dedicated travel day on each end of my hike. Once I get further North, it will probably become too much for a single day's drive. I'm also concerned with wear and tear on my vehicle, and always worried about vandalism.
I've researched public transportation up through NY and it looks like a viable option. Basically Amtrak into Penn Station, and some form of train or bus to a trail town, and all can be accomplished within a day.
I'd love to hear experiences, do's/don'ts, or any other wisdom from those that have walked/driven/travelled before me!
