Tigers, browns and black snakes are spread over mosst of the continent, we can get hot in summer but very cool in winter, we are now getting a few mild days but cold nights, the sun will always bring a few out.
They don't worry us much and we get mainly tigers that are fairly timid unless cornered, the blacks will rear up at you and look fearsome with the bright red belly but turn tail and run as a rule.
There are several dozens of other types spread around like copperheads and adders, a few pythons and some unique to each state.
Trust me, mother in law frightens me more.
