I will just say this - I coach youth kids and we travel quite a bit. Yes - the costs can add up, but if the above trips are accurate, then its not that much more than we've done. Renting a few vans (which we've done), diving hundreds of miles (which we've done), staying in reasonably cheap hotels (again, we've done, but I prefer at least a Hampton Inn level ;) - so not that much diff) and eating 3 squares a day. You're talking about a few thousand a trip. Im with Pirate - the "reasons" given by the AD are bogus. Even if you're right, Pinnum - thats 4 trips. Thats not that burdensome. I wrestled at Pitt and when we went on trips, there were a lot of parents that kicked in and bought meals, contributed to upgraded vans/hotels, etc.
And, again, like Pirate says - they have a conference option that they choose not to be a part of.
Like most of these situations, I think that these schools are making excuses for dropping the program and its mostly because its just easier to do that than to put some work in and figure out how to make it work.
Im a bit bitter about this topic, sorry. Back in the early 90's when I was in college, there were a lot of programs dropping (Clemson, for example) b/c of the way Title 9 was being applied. It was (and is?) being used as an excuse. I believe in the basis for the reasons for Title 9, but the application of the rule has crushed men's wrestling, gymnastics, tennis, soccer, dodgeball, etc.
