How about shooting an bow and arrow from the sporting goods store or an Estes model rocket from the toy store attached to a length of fishing line. Then you pull accross a heavier rope or cable. Now you can set up a little rig to ferry ammo and food back and forth.

The problem with trying to dig in and wait it out is that eventually you are going to run out of food, ammo, medicine or some other critical supply. Or negligence, internal conflict or some dumb plain ole mechanical failure will eventually lead to a breach in security and in come the zombies. Chances are your long-term presence will have attracted a fair number of the walking dead making it extremely unlikely that you will be able to escape.
Of course the flip side is that if you are on the road, you have little protection from zombies, bandits, gangs or rouge National Guardsmen if you break down, run out of gas or are caught away from your vehicle.
But either way, you are better off being far away from where people are.
I think people love zombie/rage plague films because it’s facinating watching a system collapse on itself. Society can be viewed as a complex system where each person is a “node” that performs a specific task. Protecting and serving the public, picking up trash, driving trucks, whatever their job is. A zombie outbreak attacks the nodes of that system, turning them against the system. The system (society) tries to fight back to defend itself, but as it fights back, it is weakened as a) attrition as individuals are turned into zombies, b) resources must be diverted from normal activities to fight/defend against zombies and c) the system turns on itself as conflicts over the last remaining available resources arise (weapons, food, transpo, defendable locations).
Eventually an inflection point is reached where the system can no longer function and it collapses. Police and military units lose cohesion. Logistical networks break down. Hospitals no longer function (and indeed often exacerbate the problem as they unwittingly expose staff and uninfected patients to zombie victims).
Pockets of resistance may form temporarily, holed up in whatever facility they were able to secure for themselves. But as I stated above, since these refuges are usually not self sustaining or stable, they too will ultimately collapse.
And unfortunately there is no equilibrium point that allows humans and zombies to coexist.
I’d rather be riding in one of these
