I usually cut after the dew is gone, but if it's a really humid day that's going to take until after 12 noon to dry, I will go ahead and cut as I ted it afterwards anyway. If I wait until noon to start then I have lost half a day of drying time. I admit dcarp that for the past three years rain hasn't been a problem here in Texas but over the last 25 years that extra half a day has allowed me to bale earlier and miss getting my hay wet quit a few times.
Speaking of rain, here in north Texas on the TX/OK border, April we got only 3". So far in May 6.97". All ponds are full and overflowing and the creek is running. :)
