What do you take with you when you go herping?
As to me:
-photo cameras
-additional lens
-food and beaverage
-mosquito repellent
-smartphone with GPS
-waders
-landing net
-aquarium net
-wellingtons
-money
-measure
-headlamp
-pepper spray
-1.5L portable plastic terrarium
-powerful torch
-raisins/banana to lure lizards
-welding gloves for dealing with venomous reptiles and to lift heavy stuff (eg. stones)
-narrow, small glass aquarium to take pics (20cm x 3cm x 15cm is ok? what dimensions are optimal?)
-magnifier
-pen with a notebook
-backpack
Of course i do not take all the mentioned stuff at once, sometimes i take only photo camera.
