In mid-January I will be attending attending a business-related hunting trip in South Texas, near Falfurrias. As a non-hunter myself I have been invited to bring my photography equipment and get some great nature shots from the blind. I am getting a 500mm f4L IS II lens at Christmas, so this outing will be an early opportunity to use the lens and TCs. My question is if anyone has any thoughts / advice on what to look for or expect at this time of year (I had been thinking of a trip in March - April before this came up). Any input will be appreciated.
