Nickel City Masters -- U of Buffalo drop-ins permitted?

Hey all, I posted this in the Niagara section of the forum, but am not sure that it will be seen much so am double posting here if that's ok. I appreciate any help you can give me. I've emailed the coach but have not heard back yet, and cannot find a number to call on the website. My family and I will be vacationing at Niagara Falls at the end of this month, and I was hoping to fit a few swims in with a masters team if possible. Do any of you know if the Nickel City Masters group at the University of Buffalo allows drop-ins? If so, are the practice times the same as what is listed on the website (Tues/Thurs from 6:00 to 7:15 a.m., and Saturday from 6:30 to 8 a.m.)? Thanks for any information you can give me! Kristin
