Four weapons:
1 - My suppressed Glock 41. Don't attract zombies with noise. High capacity. Accurate.
2 - A suppressed AR-15 with decent optics, the whole thing set up for medium-long range shooting. Same as above, but also good for hunting.
3 - A sword. Preferably a rapier or katana. Silent, and don't need to be reloaded.
4 - A good multitool. A toolbox in your pocket is useful.
Transport:
The Jeep I built a few years back. It will go literally anywhere.
Hidey Hole:
The 150 year old maximum security prison 30 miles from where I live. 40' high stone walls - zombie proof. Easy to clear out one cell at a time, which would make room for hundreds of survivors, allowing the possibility of starting a new civilization.
Some variant of this is most likely to be what will work.
Personally, I like 9mm for more ammo availability, yet 45 is a close second I would believe.
A range weapon, and the rifle is a good choice, as is the bow, ammo being the limiting factor on each.
A sword is good as well as it is a weapon that keeps working as long as you can swing it. Which goes to the lighter swords.
The multi-tool is a good choice for last minute blade usage to a tool box on your belt.
Of course the predisposes that the cure is not readily handy and I would take one for me, enough for family and friends and then as much as I could carry to distribute to others. And then food to help in the traveling. Of course the weapons above would help with that as well. As other humans will be as big a threat as well.
vehicle. The old diesel jeep with an aqua air intake and exhaust. The short frame and 4x4 could get you through tight European cities and through the country side as well. Diesel for fuel source and using bio diesel for fuel source as well.
Hide out, would be nice, and space is a great place assuming that the virus or infection is contained and not with those in space. Otherwise, one needs a place that provides cover and allows you to see the enemy as they approach (* Clear the country side around you *) and also has hidden exit(s) that only you or a few know about.
