This section of the forum has lots of requests for new activities (including at least one of my own). I'd still like Snorkeling (which is significantly different than SCUBA...), I'm not sure why there aren't simple entries for standard and recumbent bike machines (is that supposed to be Indoor Cycling? What the heck is Virtual Cycling?), and lately I've been back into Pool Running which isn't super common but has been around for decades, at least. So instead of having all sorts of people requesting their own random things, why don't you just let us create our own? (!?)
Because, really, Wing-Suit Flying?!?
