I don't have a gym that I am a member of so I really don't have a horse in this race. I was made aware of something really awesome that Planet Fitness has changed in their employee handbook due to our weather here in Texas.
We can always use the moisture. No matter what the form of it is. I would prefer the rain over the snow. That is because here in Amarillo it is hardly ever just snow. We usually have the killer winds to go with it. Oh and more often than not we have the ice as well.
