for what? or whom?
It was peak hour last night for sandflies after our Street Series finished - haven't had sandflies for 30 years (in NZ ).
Ooh, sandflies are horrible. This was peak hour for runners, walkers and volunteer gardeners, none of whom appeared to work ordinary hours.
However, we have had peak month for mozzies down here. It may have even been peak year or even peak decade!
Unfortunately sign of the times.
