>'Likely closer location' sounds promising, let's try that.
>You make a rough estimate of where your original path might have taken you after it headed east from the river and aim in that direction, heading northward. This is a very rough guess indeed, but you hope that once you pick up the scent again, you'll have a good enough signal to go by.
>You traverse the rest of the pasture, past what few more cattle remain, and slip into the woods beyond them. As you do, you raise your guard for unusual noises or other things you've come to associate with the spiders. Still, your previous flight from the woods was spider-free for quite some distance north of the pasture, and the return trip appears to be similar. It takes some time before you get any useful wiff of the scent you were originally tracking, but it does eventually happen, perhaps 15 minutes after entering the woods. You aren't certain if you've ended up north or south of your original route, but the lair, or at least what you believe to be it, is definitely northeast of you now and still quite some distance away. You've yet to see any signs of spider activity.
