Is summer really hear!

What about this weather??? It goes from hot to cold to sunny till not so nice out. I wish it would make up its mind. Have a show this weekend I hope it isn't to hot. Need to have the A/c in my car recharged... Will have no worries about the heat then But taking along water bottles and ice bottles just to be on the safe side. Hoping to do well at the show I really don't have to much to show just babies.
