If the blood is coagulated and their lungs don't absorb oxygen, then their bodies could not produce adenozenetriphos-phate, a vital catalyst for muscle contraction. - Zombies are impossible.
*shakes fist*
....
That aside though, it depends.
Slow zombies: First off I'm going to assume I know basic survival skills and am fit enough to maintain my bodyweight plus 20lbs or so.
I would make sure I had a building close to a pharmacy and an munitions depot plus at least two stories up(if you can get access to a roof, it'd be a nice additive for multiple reasons. - I have adequate weapon handling skills for a Canadian so with that I'd be pretty set. I'd also have a Bo-staff for nudging zombies out of the way.
This building needs to have one elevator shaft and a set of stairs. ride the elevator to the top and disconnect it(make sure it's easy to reconnect) and then tare down the staircase leading to the floor level.
I won't get into the supplies you'd need, they're seemingly obvious. The place in question needs to be big enough for 4 people comfortably, no need to travel with more people then that, and a rope ladder sufficient for three stories in height for trafficking and scout return - use the elevator for carrying up supplies.
You'd if traveling with other people, need to establish proper communication and routing methods for getting to the meeting location as fast and as safe as possible. Perhaps engineer a point to point route that takes all of your locations into mind.
That and for extra I'd have growing supplies (I'd need my weed for chronic migraines.)
Once things settled down and civilization has collapsed pharmaceuticals will be the new world currency, so like mentioned before be close to one for raiding purposes.
Fast zombies: Totally different story. A gun with a single bullet and a tab of cyanide. Fuck fast zombies. Fuck them hard.
