Yes it was helpful, I never have camped in a park I just been lucky I guess but with the kids along we try to check what the weather will be like for a few days in advance. Surprises are nice but not ones that can strand you or be life threatening.@jc banks glad you found it helpful. When you camp in parks and the like there are better opportunities to protect yourself. When you are in the wilderness it is a different story - there are no buildings to escape to. More than that the environment is against you.
