RE: edit Rat Race Club edited by Starstuff 1 day ago diff Summary: Ron wouldn't have been able to bring Scabbers if that were the case. Also this may be a metaphorical sense of "rat race," i.e. a business or young entrepreneurs club, rather than a literal club for racing rats.
Agree, it could be anything. The Wik defines Rat Race as "an endless, self-defeating, or pointless pursuit"   There is also the John Cleese movie from a couple years ago by that name  and various songs which either have it in the title or lyrics. For all one knows, it could be a therapy group for kids that feel snowed under by tedious repetitive school related tasks. (Vaudree (talk) 18:44, February 27, 2016 (UTC))
