What do you think is a crappy place? Too small of a population? Larger metro area but too many SJWs/feminists/careerists?
I believe that dating at age 25+ without a social circle isn't viable is the metro area's population is under ~100,000-150,000. Men can change their dating outcomes by moving from a smaller area to a larger area in many cases.
Sometimes, an area can have problems when it is too big and the women get too entitled/fussy. This happens in a lot of big cities in Western nations.
The women types of women in a populated area can ruin dating in the area. DC/San Francisco/Seattle/Austin/Portland are overrun with SJWs/feminists/careerists.
A crappy place is any place where there are more men than women not only for the ratio itself but for the vicious cycles it starts.
This happens wheter we talk about the micro environment (the club, the bar, the class) or the macro one (society and social norms).
Dating above 25+ is fine as long as there are enough women even if you have to approach unknown women at a club or a bar...even at the bus stop.
The issue is when in your own social circle its 10 men, 5 women where 3 out of 5 are taken with the top guys, 1 is ugly and the last one is the side chick of the cool guy of the group.
You will notice that places where there are enough women and enough competition among them produce better women from any possible point of view wheter its looks or behaviour.
Places which are a sausage fest produce ugly, annoying women where you have to force yourself to deal with them.
It's no coincidence that there is no mgtow in poland or czech republic while it's explodind in canada or the us....after some point no matter how hungry you are, eating rotten food is worse than starving.
