You’re in a great area to get into aviation. Arizona is a very aviation rich environment, especially Phoenix and Tucson. I have heard there are some great EAA chapters in that area, and I know they are constantly restoring aircraft at the Pima Air and Space Museum. The museum would be another place to go to meet and talk to people about aviation. And the retired vets/museum volunteers will talk your ear off if you let them.
Here is a link to EAA chapters search. Just select AZ and scroll down. Probably the 2 closest would be EAA chapter 81 based at Ryan field there in Tucson, or 766 in Sierra Vista. You might give them a call, email, or Facebook message and get more info for meetings and Young Eagle flights.

There are a few air shows and fly ins coming up very soon around Southern AZ that are open to the public and are usually a lot of fun. Buckeye Air Fair is the soonest in February 17-19, although Buckeye would be a bit of a drive as it’s on the west side of Phoenix. Then March 25-26 there is Thunder and Lightning over Arizona, and that’s going to be right there in Tucson at Davis-Monthan AFB. There are other fly-ins throughout the area that will also be open to the public.
There are many great suggestions in this thread. And you are in a great area to completely immerse yourself in aviation. There are tons of aviation opportunities available.
