sightings of a rainbow

this is a rainbow i saw that day while cycling. was going to the train station and cycled thru the 'ringpark' which is a park that surrounds the city centre in a semi-circle with the river on the other side.. apparently this is a fairly common sight but it was so pretty i couldn't help but stop to gawk abit :) the ring park is beautiful in the day but at night lots of drunkards lurk in grps there.. was cycling thru it one night and got abit freaked out cos there were grps of 10 men and the park was not lit :/ only light was fr my bike.. and today walked thru the park again and got slightly lost :) ended up at a different part of town, but saw some bird cages, ponds, sculptures etc.. looks like there's lots of the ringpark i've yet to discover!
