It would be good to have a couple separate podcasts from separate people, who've had experience sucessfully doing day game on a university campus when they were attending and another one on doing day game in a gym, as both are probably the hardest day game to do. Gyms can be very frustrating, as most people seem be shut down from being in a sociable mood, plus some gyms can have much more frustrating logistics than others. In theory, even if you're in a gym at night, it'd still be day game.
With colleges - universities, depending on how large a campus is, indirect approaches are probably the best way to go, in what's a closed environment, as you don't want to be seen as the pickup guy. For guys who live in Europe or Australia, it's a lot harder as they don't have the social circle advantages US colleges - universities have (fraternities - sororities, dormitories, varsities), plus women approached can complain that they have so much school work and study to do, they have no time for dating and for having a social life and it can be valid. There's also the fact that if a guy is serious about getting good grades, he won't get them if he was going on a 3 or 4 dates a week.
