UMA was mentioned many times on RCU, but it seems that everytime the subject of UMA came up, it was either totally ignored, suspect or dissed and/or compared to SFA. Then again, as mentioned before, most if not all AMA members considered it illegal to allow UMA members on an AMA field. The only way UMA could succeed was the creation of many more UMA clubs. All and all, IMO, there just wasn't enough people in the hobby/sport in general to make a difference, one way or the other, not to mention those who have had it with clubs altogether, whether they be UMA or AMA.
