well I'm not going to lie to you, there's going to be a BIG difference between Wisconsin and California that's for sure. Starting with weather. You're going from a place that sees maybe 3-4 months of warmth a year to a place that sees around 10-11 months a year of warmth and heat. Deer typically are stronger in numbers from the midwest and the northeast on up north towards Canada. You just don't hear alot about California Whitetails. However, they are there though, your hunting is going to be tougher though. Another thing I have heard is that if you do see whitetails out in california they are not as big as they are in the midwest/northeast/northern part of the U.S. Good luck to you, and have a good time in California,,,Gob bless!
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
