Cancer Society staff will be at Wanganui's Riverside Market tomorrow to catch anyone who can't donate to the cause today - Daffodil Day.

"If people are busy on Friday, they can come and spoil us on Saturday," said Wanganui manager Simon Aitken, here with the society's community health adviser, Jane Beamsley, in a drift of daffodils.

For those who can support the Cancer Society's annual appeal today, there will be 23 booths around Wanganui, plus a barbecue from 10.30am onwards at Majestic Square.
