Indeed ! I have been thinking this for several years now. Surely many of us can remember those windshields. It can't be all better air flow / design ?

A phone message, may be brief!

For the past 30+ years I have made regular summer car trips from St Margarets Bay to Fredericton; in the early days I used to frequently have to stop to clear accumulations of dead insects from my front windshield. I am no longer sure about the exact time frame of this change, but yesterday on return home I was struck by the total lack - not one single insect on my windshield, which speaks such volumes about the enormity of change happening around us - and also how easy it can be not to be so quick to notice or object to the 'convenient' changes...................
