My ride is a little over an hour and I usually am underway by 5:25 AM. Getting calls then isn't an issue. I try to leave around 4 or 4:30 in the afternoon so it is quite possible that I could get a call. I usually put the cell in my jersey pocket on vibrate. If it's convenient, I'll answer it should it ring. Otherwise, I'll leave it until later. I mean unless you own the business or are really a pinnacle person in some deal, or are the only resource for customers, how important are these calls really?
