There are a handful of women that come on the faster rides in town. They pretty much act like "one of the guys" most of the time. One of them has the foulest mouth of any of us

Maybe some shops/groups are hostile to women, but in my experience we don't usually care who you are as long as you aren't dangerous. If you can hang with the group that's a bonus but plenty of people (men and women) get shelled and if you keep coming back week after week that's cool
