I won't know until tomorrow if I can be there by 4. I'll have to see if someone can come in to work for me so I can leave early on Saturday. I'd have to leave work around 3-3:30 to make it there. I'll find out tomorrow.
Is there any reason why this can't happen on Sunday or later on Saturday? I haven't seen anyone say that they couldn't make it Saturday evening or Sunday, and I'd rather not have to leave work early and be rushing if everyone is fine with another time.
