Waited for about 3 weeks in No Name one year, but that was my first year and everyone was waiting. Basically you need the wind
to go south of East, SE should be fine.... Or for the prediction to be no wind
... If memory serves "no wind" is usually the SW or West "wind" which is when the wind is clocking or no established system. It may stay NE for days, but once it changes toward the south from NE or E, git 'er done! You need about 8-10 hours to get across. Have I got this right?
