I'm too old and privacy conscious to partake in such activities as Tinder, so I do it the old-fashioned way. Volunteering at the local library and hanging out on my local river trail has been been the best way for me to meet potential partners. Bars were quite effective until my mid-30s, but things change as people age.

Also, I bet the West Slope of Colorado is different, dynamically, than NYC. I live in a town, not a metropolics, so that has to make a difference.
