Well I'm finally taking the plunge.... After reading and re-reading this thread I am building my first UDS. I can't wait to actually smoke some butt.
Bought me a couple of orange juice drums for $20 each on my way home from Las Vegas. They have a tan colored liner in them. I'm going to start with one then after getting one up and cooking I will see what I want to do the same or different with the other one.
Thanks to everyone who has contributed to making this incredible UDS thread!!
