Like all sequels this one isn't quite as good as the original. The rock isn't really even a rock but at least it isn't likely to float away.
This area is mostly deserted 99% of the time...unless there is a game so while "stealth" in the typical parking lot, LPC by the front door sense, isn't usually required here it is a very popular area particularly with dog walkers (or just walkers) so be on the lookout for other people.
This is a very small micro cache so you'll need to bring something to write with and tweezers to remove the log are a good idea too.
