We opted to do the shorter route which worked out to be a little over two miles, five seemed a bit much for Seal Pup 1.0. And while SP1.0 was very excited about "hiking in the jungle!" we wish he was as excited to actually walk, or rather, hike the hike.
There was a goodly amount of shoulder riding; but, that's okay, he is only three, after all. And since Seal Pup 2.0 didn't have to do any walking whatsoever, well, I guess I can see where he was coming from.
