I think a big part is T-Nation requires your info. Like you cant just go on here and pretend your somebody else.
I mean if your city is listed, its not hard to figure out which of the clubs you train at. If your as good as you say you are, somebody lurking could just call you on it.
When i travel for over a week and stay with a friend, ill tend to bring my gear with me and do drop in's to train at different schools to learn what i can. I mean if some how i ended up in Arkansas i'd ask Melvin what club he was at so i could drop in.
Being held to the truth tends to reel back the desire to BS.
