OK, I was reading a forum and they mentioned pregnant women due to give birth and roads to the hospitals are congested. So, I remembered a situation when a country ( possibly Australia , can't remember for sure) that had a planned international sport occasion (can't remember what it was, world cup or whatever) issued a suggestion to its citizens to be careful about family planning : meaning NOT plan for pregnancy the next weeks because birth will be due in the worst time when all roads are jammed

I don't know if anyone remembers that country or the occasion or year
