Why do so many people suggest tunnel time if the actual time in the tunnel is so limited? I mean, I understand that freefall time is pretty brief as well, but if I want / need the practice, why do the time slots come in minute or two increments? What is the physical toll? Similar to or worse than freefall?
I see that there are actually three in the works (Philly, Manhattan, and Xanadu in NJ) in my area, but that New Hampshire is the closest (thanks, Howard). If I were to make the drive, what should I hope to accomplish? I want to know as much as possible before committing myself to the drive!
AFF 2 and 3 are tomorrow so I clearly will not be able to make use of the tunnel before then, but for future reference or for winter use, any advice on tunnel time would be greatly appreciated. Thanks.
