Do you work for MENSA Lol Like i said i don't believe the 7 year cycle theory, If a warren gets effected then all that's left in theory is those that have recovered from it, Allegedly immune, Its not until new off spring have increased the size of that colony that the virus spreads again, The road could have stopped interaction between the two colonies, Thus those on the other side of the road would have had no immunity, Maybe in a few years it will wipe that colony out again,
