I was up Arthurs seat but it was blowing a gale and my tripod kept rocking. I'm glad it wasn't just me that had trouble with longer than 2-3 second exposures.
A common trick to help stabilise a tripod is to hang your camera bag / carrier bag full of bricks (whichever is heavier) from the bottom of your tripods centre column.
People get spiky when I suggest the support needs to have some weight to it to stop it vibrating and ruining the shot. Then I gently remind them that their $3938472 tripod is still a good purchase, just hang a heavy lens (or the entire bag) from the hook and you're golden
Also.. if you're going to all the trouble of setting up a tripod... use mirror lock up if your camera has it.
I was on the bike so travelling as light as possible so nothing heavier than the tripod to hang from it. I have been thinking about a way of rigging the bike up as a mono/tripod but that wouldn't have helped where I was. I don't have mirror lock up on the D3100 but quiet mode makes a visible difference to the shake at the expense of slowing down the shutter response time, not an issue for most shots but a pain for fireworks.
A few of them weren't bad 4 "good" ones and a lot of rejects. These are my favourites DSC_2796 by steveo_mcg, on Flickr DSC_2809 by steveo_mcg, on Flickr
