Perhaps it was good it was a cool day and they were less likely to be out and about though it did claim they might bask in the sun even on a cold day, once they were out of hibernation. There were more things to invoke dread. If you are agorophobic proceed with caution or, not at all. The raft spider lives here and though harmless to humans it is the largest one in Britain.
