Do you have a particular interest closest to your heart? Contact them.
I discovered a lady was making cage inserts for a local animal rescue group. You adopted a critter, you got a cage mat. The mats were even sometimes time of the year themed: Valentine's Day, St. Patrick's Day, 4th of July, etc. Encouraged adoptive people. I discovered the group and this lady at the vet's office.
There are groups everywhere. Find that interest closest to your heart and talk to people who are involved somehow with that interest. They are out there and all it takes is talking to people to find them. Your time and talent will be gratefully appreciated. And you will make some similarly concerned friends.
Good luck and have a good time.
