If you're in your mid-20s in most US metro areas (except in the South, perhaps) - this is what it's like.
Says who? Have you stepped out during a weekend in a US metro city? To popular nightspots? No app needed to meet and socialise with attractive people - strangers or an extended social circle. In fact some might even say it is like shooting fish in a barrel
If by “some” you mean females in their mid-20s, then yeah probably.
