1. It's beautiful here. You just might turn a corner and find a beautiful fountain shooting water into a pool. Or breathe in and smell a floral aroma you've never smelled before.
2. There are A LOT of people who like to exercise in the park. Research the proper protocol on running around and past other runners or walkers. Also, know which side of the street/path to run on. These are things I still don't know.
3. There are many many many trees. Most of them are tall, obstructing your view of such things as Regent's College, where I live. Make sure you know where you're going unless you enjoy long cool downs while you try to find a map.
4. In case you don't heed the warning in #3, don't be alarmed when the person you ask for directions answers with a British accent. Remember, you're in England.
I figured that you should know these things I didn't know before. I learned numbers 3 and 4 this morning. Regent's Park is BIG.
