Shadowbob, I hear ya there. At my previous job I was always (365/24/7) on call. The plant manager didn't seem to get the quiet solitude part of hunting. I would respond to his calls with texts. The guys who worked for me got it. Wouldn't bother me unless they had no other choice.
New job, still on call always, but get a call every month or two, not ten + a day.
So to the OPs question- yes I have texted while on stand, but only for work purposes. And my age is 36.
