Sportsfan98,
I totally agree your response with some dedicated watchers that never hesitate to take a chance to take a good picture or more.
Since I started for some years ago something has changed with more secluded areas and increased facilities around festival area. Our only possibility so far is to use the camping area where you could work without any attention from other people.
There are too many agoras on east side to discover and we have no possibility to take an overview everywhere.
Do you feel that you could catch up with this effort you are welcome to spend a week in Roskilde.
