When taking the boat, not only is it the same distance to the boat dock as to the IG, but once on the boat (if that's the way you choose to go), you have to ride over to BWV before you get to the IG. Unless the boats change the way they go, one day I sat on my balcony at BWV (for hours I watched) and noticed-every boat from Y&B stops at BWV before going to IG. Yes, we DVCers sometimes lead exciting lives!
What is exciting though is that not only can you see a snake on the path behind BCV, you can also see one sometimes by the bus stop. There's one that gets up from the canal, then gets "stuck" inside the paved walkway. Boy, that one got the ole heart rate up!
