It would be fair to say that I'm having a barren spell at the moment.
I think this dates from a period that was quite the reverse back in July. Anyway current spell due to reasons various and common: fog; darkness falling; heavy machinery starting up nearby; out of range; out of season. Not that I haven't enjoyed my stalking, it's never been about just shooting deer for me and I love having seen deer (often very close) and wildlife that I would never have experienced otherwise.
So come on, please make me feel a little better, what's your longest spell of blanks?
