I have uploaded Arsenal with the new background.

Also, Mike and I have decided that I will just overwrite his parks because having two versions is too complicated especially if/when doing future updates. I have removed my (2) version that I previously uploaded and replace Mike's with what I have already done.
If anyone decides that they prefer the old background version after I update parks just send me a private message and I will make Mike's latest update available to you.
