Nathan,
You would have a long haul...driving to/back and four hours in, say another 4 to get out. at least it's staying light out later and I don't think you would have to run it at night
Heading back out the same say it would be advised to get someone to make the trip with you. It's not a bad trail, but you may run into something unforseen. Just my .02
