You're looking for a micro-sized container, so please BYOP. Overall, there's some latitude in the D rating, but it reflects a new to average cacher attempting this in the middle of the day. It's a challenging cache to nail down a D rating to, because the variables involved are quite fluid. Remember, you'll be watched from all directions, so try to blend in. 
In our Caching Around series we've created hides that span the full spectrum of the Difficulty Rating, including the half-stops. You'll see the listing below, showing the difficulty rating then the Caching Around series number. Click on the number to be taken to that cache page. If you're new to the series, why not start at the 1.0 and work your way up to the 5.0 cache. You'll even be able to complete all the ratings by selecting caches that are in geographical proximity. Happy Caching Around!
