Take the biggest kite you have or save your time and don't bother bringing anything.

I'm just jaded but I'm starting to lose interest in kiting because I feel our wind is ****.
If it's windy, you'll have rain squalls coming through. If the airport is reading 20 knots, I'll drive 20 minutes to the beach and it'll be barely worth inflating the kite or worse...you'll get set up and out on the water only for the wind to die 5 minutes later.
And then days the airport is reading 10 - 15 knots, I'll just go for a walk and it's blowing hard.
4 mile is a nice beach...for riding a bike along

. And if it's actually windy it can be fun.
Hope it does blow hard when you're here.
