What's your rig setup like? Even if your rig may not be up for Swamp, the first night most camp at Dinkey and there are about 3-4 other trails that are not quite as hard.
Like Chuck said there are other trails, I've been on Strawberry Lake trail and it's a great trail just right. Bald Mts. it's also a great trail not to hard and any of the trail up there have great veiw of nature. I will try to make it to swamp and dusy this year as well as the rubicon.
