I am new to hunting but i have been fishing all my life and comfortable in the outdoors. I never did get to go hunt growing up. Now my children are getting older and I see that its now time to learn how, so when my boys are older I can show them that experience as well. I have very little knowledge about the rifles, permits, licenses, and any equipment needed so any advice would be helpful.

Here is my hunting situation thou:
I live in am 25, live in Texas, and plan to go hunting in south Oklahoma next winter when deer season begins. I have a family member with about 90 acres of land and permission by them to go hunt on the land. So I could put up stands, feeders or anything like that if suggested. I'm not sure of what type of rifles I should look for. The land is about half field and half forest. I also need to know what type of licensee i need to be able to hunt in Oklahoma.
