If I have operations going on I expect (or demand) a call and report from our foreman before the end of the work day. So if I go riding in mid-afternoon I put the cell phone in my jersey, set it to vibrate, and go. I'll slow down or stop as needed. Quite often in the hills around here I get the buzz that he called, but then have to stop on a hill and call him back. Also, my honey will often call to ask what time I'm coming home. Nothing strange at all about using a cell phone while riding, IMHO.
