Well done, Massimo!
I remember you commonly see viridiflavus around your house, and you have also seen nearby a couple of longissimus mating or fighting, if I remember well...
I have the clear impression, but it's more than an impression, that your places are much more well preserved than mine. A similar situation was the one I remember near my home, in Oltrepo' Pavese, but during the '70-'80s: now, on the main roads, you find absolutely nothing at all of reptile life, neither living nor dead!
This is due to many negative factors: intense road traffic, wildboars more common than years ago, mass tourism, pollution, and so on.
Probably, in your region, all these factors are less pronounced and, besides this, you have probably much more and bigger untouched woody areas around your home.
I warmly suggest to you to make some night road herping tours during these warm days: you will be certainly not disappointed, and, if you see a "Will o' the Wisp", you have my phone number...
