I like to take pictures on the way home from work, but I don't want to bring my camera into work with me, because we have had theft in the building. I've been leaving it in the trunk of my car. Recently the temp has been in the 20s and 30s. Is it bad to leave it or the lenses in the car like this? What about when it's hot out? I think it would be bad to leave it in a hot trunk.
