Help needed to learn...

[drewmerc]

1. about 7 mile but it depends on many factors (quick example if i walk a 100yards east of were i am, i will be on a different node but walking west i have to go all the way to the other side of town before i hit another. the point of this means knowing how big a node is, is pointless you need to know where the boundaries are)
2. no not on same node
3. ordering a pre mod is stupid as you learn nothing and as always at some point you will need to reflash
