Great job and congrats to all RAMROD riders - am sure it WAS tougher - whew!
Yes, the tube sock is a great idea and my PT/coach who rode RAAM some years back, gave me what she used in the desert before I did an AIDS ride across Montana. It's a modified pillow case, (you can make 3-4 out of 1 case) cut and sewn into a tube leaving the opening intact, putting velcro fastener there, so you can open it, fill it up, close it around your neck and keep going. It doesn't stretch as much or flop around like the tube sock did and those cold drips on my quads as the ice melted while I rode was a godsend!
