Stop in for a cup of coffee

What realy sucks I have 25 gallons of roundup mixed in the sprayer in the tractor bucket have to spray that with three hours of no rain.
I need to do some weed killer spray too. Not roundup brand, but I think it only needs a few hours also. At least it's not 24hrs like the granular stuff for the yard. Tough to catch that long of a break between rain lately
