Ahem, as I said, money is irrelevent...period. Capiche? I don't care how much, or how little, moola a prospect's father has, if there's not genuine interest then that father who has all that coin isn't going to throw it away for a one-and-a-half-day visit. Daddy Joe isn't an idiot. He'll send his son on unofficial visits cross-country only, that's only, if he feels there's sufficient interest in, and proper value to, his son.
Keep in mind that the visit, although being on the weekend, does take away from his son's high school studies, so Daddy Joe doesn't take this lightly and it must be at least fairly important. As for "gathering more information", most prospects don't come to the spring game for "gathering information", but rather they come to see that Ohio State brings more fans to a glorified open practice than 80% of colleges bring to a sold-out home game.
If a prospect who otherwise couldn't afford to come to the spring game, then they'd get an official visit (provided they were high enough caliber, and an official offer would suggest that).
So, my original comment that it must be important to the Montana's if Nick is coming out on his own/daddy's dime stands...and is correct.
