John, I made up 4 pvc trees a year ago and never dropped them anywhere. Kinda tough to do in the yak and never felt like taking my dads boat. Anyhow, they are cemented in 5 gallon buckets, just need to cut the holes on the main pvc and slide the limbs through. They are all about 6' tall, about a $100 in material total. If they allow it I will be more than happy to let you guys sink them in LA. I have to be in san marcos on the 11th early but I can drop the trees off to someone if they can take them to LA.
