On our first expedition through this park, my two kids and I stopped for a while to wait for a passing train. Alas, none came while we waited. Walking down the trail a bit on the way back to the car, we saw a good spot for a hide and, me being the well-prepared geocacher that I am, I pulled out the goods and placed them near the three-way intersection of trails.
It's a good-sized cache with plenty of space for swag and trackables. There's also a pen inside...but surely you know that the cheapo pens aren't always reliable.
It's in a wooded area just a short hike up the trail to view passing trains..
PS - If you're into Benchmarking, I happened upon a nearby benchmark during a recent visit to the site to check the cache:.

It's just up the trail near the tracks...surrounded by scrub, but easily visible by the orange marker post.
