Towing again

Went out on Sunday and got some more tow practice. Jason was first up and got a great tow but couldn't stay up. I suited up and was soon pointed for the sun. The tow was going well when all of a sudden I went from a 1500 fpm up to a down in the blink of an eye. First time I've gone negative on tow. It was a little unnerving but after flying Golden, a non issue. The thermals were big and slow but between thermals was rough. I hadn't planned on going anywhere and after an hour was bored of fighting the wind and not getting too high. On my way down I did few high wing overs and told Jason I was aiming for the road as a spot. Into ground effect I didn't think I would make it, but soon it was time to flare and the road was right under me. Dead on spot landing in my books. Jason was soon on the line and it was his turn to go cross country. His first one. He did well and I picked him up 15 K down the road.
