You can't use a barracks to wall in here. Your SCVs will be doomed if you get dropped or recalled

If you know how to make walls you will notice that many of these walls can be adjusted to be zergling-tight! I hope this will help some terrans out there.
Oh and I noticed one thing as well:
+ Show Spoiler +
If you spawn at 7 you will be able to wall off the entrance between you natural and you mineral only using 4 supplies...
![[image loading]](http://img21.imageshack.us/img21/5425/natent71.png)
or 3 supplies + barracks. You can simply wall in at your natural and when you want to take your third, you lift your first barracks and land it right here.
![[image loading]](http://img94.imageshack.us/img94/3290/natent72.png)
If you want to wall off your entrance when you spawn at 1 you will have to use A LOT of supply depots! And if you walled in your nat you probably want to mine the mineral patch and destroy those depots next to it, or you army may get stuck. Probably not worth it.
