...and i was planning on that as well as doing some hiking.
Been thinking a bit more about what I did my one trip out there and offer some additional thoughts. If you do some hiking up river, you can usually get above most other anglers and find much open and likely water. I walked for maybe 45 mins. on the West side and found some great spots. However, before I went, I spoke to some people that have fished the D and here are some tidbits:
There can be some rattlesnakes and given there are some stretches with tall grass, walk with a heavy foot so the snakes know you're coming and will be prone to slither away and hide before you get to them; a startled snake is probably very bad for your health.
There can be lots of ticks. I wore a pair of synthetic running tights under a pair of cargo shorts, tucked into long socks and a long-sleeve synthetic running shirt, tucked in to the waist band. This attire was meant to keep the ticks off.
Wear some light shoes you don't mind waterlogged and just wet-wade. The rock structures can be sharp and slippery, much different than the freestone rivers I'm used to, so just be prepared for vastly different footing.
Bring water. It gets really hot.
Fish early a.m. if possible because the water can warm up considerably and the cooler water in the a.m. might mean a better bite.
