OK...here is what I would do.
go to
www.jurisdictionary.com and learn how to do it yourself. File the cause of action, motion the court to do a lot and hopefully one of them will pay. Most want to settle rather than hassle with a lawsuit...and you can motion the court to excuse them. Find out who owns the van, sold him the liquor and let him drive, name the hot chicks he was showing off in front of just cause you can. Use the legal therories of expanded and extended laibility to find the deep pockets...even if it Anhauser Busch.
I would also keep hassling the insurance companies and elevate your claim. They always sao NO right away to anything that looks expensive.
Move your home 1/4 mile off the road with a winding driveway and lots of trees.
I am so sad to see that burb hurt.
