I used to wait until about the middle of June to put my cameras out but I actually went yesterday and set all four of them out. You really won't get an accurate idea about the bucks rack-wise until the middle of June but it does give the opportunity to see whats out there and give you a rough idea about deer movement. So to answer your question, anytime's a great time for trailcams.
