Sixteen winners were presented with grand prizes Monday in the United Way of Buffalo & Erie County’s eighth annual United Way Challenge. Winners were chosen from among donors who pledged at least a dollar a week to the 2013 fundraising campaign.

Winner of a trip to Kennedy Space Center in Florida, donated by Delaware North Companies, was Elaine Kaminski of EMS Group Stahlka Agency. A Sports Fanatic Pack, including Buffalo Bills season tickets and Buffalo Bisons Friday Night Bash tickets, went to Peter Hoffman of the state Department of Transportation.

The others won $1,000 Evans Bank debit cards, $1,000 Wegmans gift cards and $1,000 Tops Market gasoline cards. Prizes were presented by United Way president and CEO Michael Weiner, United Way campaign chairman Dennis Black and WGRZ-TV anchorwoman Melissa Holmes at ceremonies in United Way headquarters.
