No, never had any problems finding a couple of trees to hang between for the night. Although, a few times my 'best site' was not ideal. That was the result of wanting to stay with the group I was with at the time. Another couple of minutes down the trail and it wouldn't have been an issue.
Much easier finding a place to hang a hammock than finding a place to pitch a tent.
I remember stopping at Partnership Shelter (so I could order a large pepperoni pizza and take a hot shower) then pressing on a couple of miles after dinner (that's eating my regular dinner after eating the large pizza. I miss being able to eat like that!) and hanging between a couple of trees on the side of the hill below the trail as it got dark. Spent a perfectly comfortable night in a place you never could have pitched a tent.
And one afternoon hiking through Shenandoah National Park I was chased along a ridge by a wild thunderstorm. I found the first spot in the trees where the undergrowth was more or less open and got my tarp up just as the storm arrived. Then I was able to hang my hammock and get my gear sorted out protected from the rain, crawled into my hammock with a book and my transistor radio, and spent a cozy, comfortable evening out of the weather. It's a great feeling, and I miss it.
