Remember the newbie who said "hi"?

I came on here in August, mentioning that I was looking into training.  I was a little bit busy at the time, but I finally found a class that fit my schedule.  I'm currently in the middle of my classroom and confined water sessions at Scuba Center (classroom last Tuesday and this Tuesday, pool last Thursday and this Thursday).  Once I get that done, I'm off to beautiful, sunny Square Lake this weekend for my open water dives.  Assuming I don't freeze to death, I should be finished by Sunday.

Speaking of which: I called the place late last week to make my reservations for open water training, and my coworker in the next cube overheard me and said I was making a mistake by scheduling open water diving in Minnesota at the end of September.  He said he did his open water dives in Square Lake around that time of the year and that he had a miserable time -- it was cold, and everyone there was just freezing.  He thinks I should have made reservations for someplace warm during the wintertime.

I'll have a 7mm wetsuit for the class, and I don't get cold all that easily, but should I be concerned that I'll turn into an ice cube in Square Lake?  I suppose I could wear something under the wetsuit for additional warmth (like Under Armour -- certainly no cotton!) if it would help.  Will it be that cold this time of the year?

Regardless, I'm certainly looking forward to getting my certification!
