Alas, I can not convince you as I also am struggling to see how this would be a "on-going discussion." Travel & Fitness issues are often addressed in specific hotel fora and/or countries. "Which hotel in Vegas has the best spa/gym/vegeterian food?" would appear to be a better fit for Las Vegas Forum than a "Travel and Fitness Forum." My concern is that the "Travel Health and Fitness" Forum may have an initial flurry of activity (e.g. Senior Travel) and than fizzle out.
I am opposed to this new forum for the reasons just stated.
