Welcome to the site.
If you can find out the owner you can look up the number and contact them. A good chunch of them are open to the public or sell use permits 
Let me toss my "welcome to the site" in as well!

And just as these guys said - I found a number for the places I wanted to go and then called. Some said yes and some say no, oh well, what can I do?

Some of the places have a sign with the mgmt company's info. The tough ones are the larger companies where you get transferred and have to call 10 different people before you can finally get someone to tell you 'no'!

But with my luck, I'll spend a month or 2 calling people with no luck but the one time I went out there to hunt, someone would catch me on there and report me for trespassing! No way! Anyway, good luck and welcome!
