Depends on weight, volume of board, experience, etc. I tend to think things through okay. Back up plan here was if the wind dropped off more, I'd downwind it and hitch a ride/catch the bus back to my car. Its been done before :)
Thursday afternoon SSE - max 30km (16kn) dropping to 18km (10kn).

Plan C: I told 2 kite mates I'd head out for a bit of whale hunting, so they'd raise the alarm if I didn't make it back.
Plan D: wait for a whale watching boat.... lol
