Guess what - rained out again on day 6 as the front moved back north.
We rigged, gridded and watched as the sky grew darker before pulling off the grid and heading back to the trailer. At least today we were able to de-rig before it rained.
A couple of sniffers were launched, and all they found was about 100 ft/min to 2500 ft. Both were back on the ground in about 20 minutes as the sky continued to darken as the thick clouds moved in.
Next contest - Canadian Nationals at York Soaring starting on the 20th.
