That's wonderful you all are settling in to a new life.  Some cats will actually walk on their leash like dogs.  Mine may take me along a fence line if there is good stuff to sniff.  But don't be disappointed if your experience is like pushing a string.  My Kitty would rather roll around and snooze in a sunny spot while I stand there holding the leash for however long I can stand it. I finally got a stroller for her so we could walk... or I could walk and she could loll while I push her around the park.  Works great, but one thing at a time, eh?
