I guess this is technically a multi, but it is nearly a traditional with a twist. You can access both stages from a single park location. The walk in is more difficult at the beginning because of all the standing water and the uneven ground. Look around though and you can find an easier way past this part.
Once you get to the first stage it will be obvious what to do next. And after you have signed the log, make sure everthing is back where it should be for the next cacher that comes along. Enjoy and be safe.
