Voldemort's Attack on Lily and James

Hey everyone

Quick question on the events of Lily and James's death. 

If the Weasley twins can learn how to Apparate and can do so in 
Fidelius charmed house (the order's headquarters), why can't Lily 
and James merely Apparate to Harry's side and then Apparate out of 
the house? Or if they cannot Apparate out of the house, why not 
Apparate to the front door and then go outside and Apparate.

I am presuming that Lily and James could Apparate, but the only means we 
are given to stop someone from Apparate is spell DD uses in the MOM 
against the DEs. We are not told that Voldemort used this spell on 
Lily and James, but granted we still do not know exactly how the 
attack went down. If you can just Apparate in the first pace why not 
just go on the run? We are not told if there is a way to track 
people who Apparate. If there were no way to track them, wouldn't it 
be safer to just go on the run and Apparate every few days? Why keep 
yourself in one place? 

Thanks

John
