How can we better the odds of getting a grant?

Follow guidelines precisely. Work key phrases from the foundation's
statement of purpose into your statement of objectives. Have any of your
board members or good friends who know any foundation board members
write them personal letters in support of the proposal. Include as
addenda letters of support from important people, helpful excerpts from
official sources, news clipppings, etc.. Keep trying.

Note: many grantwriters swear that success requires establishing a
personal (by phone) relationship with someone at the foundation.
