Where do you do day game? I now live in Boulder Colorado and I went to this street the other day that you can't drive down, just for walking. Tons of shops and people around. Still not many girls to approach. Was sad. Sometimes you'd have to wait 5 to 10 minutes before seeing a hot girl alone. I used to do day game in Madison WI on a similar street and the amount of girls was way higher. Does every city have a good day game location or no?
Ideally the place would have so many girls that you can go right from 1 to the other
The only place I've seen going one to the other consistently is in the center of big cities, which Boulder is not.
IME, the best place to go is in high traffic areas where there's a waiting spot... like subways or popular grocery stores, potentially malls at the right hours, McDonalds, places like that.
Many places have a "route" that you can go... did they end up building the light rail up to Boulder? You might want to go from college campuses to Whole Foods to parks to that street in the middle of downtown... don't remember the name but it's usually packed with people on the weekend and they're playing drums and whatnot.
If you're in Boulder, they probably have a sex party scene but you'd need someone to introduce you to that.
With a population size of 100k, you'll probably end up overfishing Boulder in a pretty short period of time. I know they have a pretty heavy tourist scene but I'm not sure if people are staying in Boulder, outside of going to the mountains.
You might want to make trips to Denver or Fort Collins and check out those areas as well.
They also have a pickup community in Boulder but I think it got dismantled a couple years ago.
