I was watching the bonus coverage in the am yesterday on the Masters App and mirroring it to my TV in my home office. For the first several hours (on my feed anyway) there were no announcers or anything. Just open mics catching the players comments and creek and bird noises, etc. Dont know if this was something they were doing on purpose, because there was closed captioning of an announcers comments if you wanted them, so someone was giving play by play to create the CC, but it did not come across my audio feed.
Trying to get work done was hard because it caused me to have to pay closer attention. My daughter (not a big golf watcher) came in and sat down in my office for a while and she said, "man I love just hearing the nature and no announcer! They should do this all the time!"
At times it just kind of felt like you were walking the course with them, hearing their conversations and not the announcers. Overall it was pretty cool, and a rare opportunity with no patrons to just have the "out walking with your Thursday morning foursome feel!"
