Thomas Kinch, 10, Amelia Briggs, 12, and Brayden French, 11, all wanted to visit the Airtime 360 trampoline centre, at Sports Arena, for their birthdays, so Thomas's father Adam Kinch said it was decided to take advantage of today's public holiday and make a day of it for all concerned.

``We came across to City Park for lunch, where they all got their scooters out, and then we're going to the Science Museum - the kids should all sleep well tonight,'' he said.

``They had a ball on the trampolines as did (Brayden's dad) Marcus.''

``I was the only adult who went on the trampolines,'' Mr French said.

``There had to be a responsible adult supervising, so they supervised and I went on the trampoline.''

But it wasn't all trampolines and scooters.

Thomas's sister Ainsley, 11, and friend Zoe Wunder, 14, made a bee-line for the City Park chess set.

Although Ainsley learned to play just last year, Zoe started when she was six.

``We had a mini chess tournament at school and I was the only girl on the top 20 - they gave me a medal for that,'' Zoe said.

For the record, Thomas's birthday is tomorrow, Amelia's is next week and Brayden's the week after that.
