yep, the second estrus cycle is usually what most people call "the rut" ... the first cycle is typically in Oct. (in most areas I have hunted, central & west) but the bucks are still in bachelor groups and not many of the does will get bred during that first cycle. That first cycle also is what breaks up the bachelor groups. One of my uncles used to start going out sitting in his tree stand the first of Oct. every day after work, when he saw the first sign of chasing going on, he would go home and mark out 28 days later (in Nov.) and wouldn't even go into the woods hunting until that 28 day came around. That was typically around mid Nov. when deer season opened (used to open 1st Sat. after Nov. 16).
