More info than you were looking for, but this topic is close to my heart: I'm a volunteer fundraiser organizer, and in the last 6 years, I have directly or indirectly, through donating money, raffle items, and/or my time, helped to raise over a quarter of a million dollars for charities including:
Toys for Tots, Local Heroes (care packages for soldiers overseas,) Muscular Dystrophy Association, Cystic Fibrosis, Children's Brain Cancer Research, ASPCA, Breast Cancer Research, Ronald McDonald House, Massachusetts Motorcyclists Survivors Fund, the 9-11 funds, the American Red Cross (Tsunami and Katrina Relief) and uncountable small, independent fundraisers designed to help a child with cancer, or a dad with cancer, or for research funding in the memory of someone who died from cancer, or a funeral expense for someone killed in a motorcycle accident that had no life insurance, survivors of house fires that have lost everything, etc., etc., etc.
I spend my summers riding my motorcycle to one charity event after another, combining something that I feel I need to do (contribute to those less fortunate than I - and I'm not rich by ANY means) with something that I just love to do (ride my Harley.) In some cases I help to organize and run the events, which gives me GREAT satisfaction.
I do NOT claim my donations on my taxes, because I feel like I'm paying my dues back to society for having had to raise my child on welfare while I went to college. I'm sure that my donations, volunteer time NOT included, probably equate to more than a thousand dollars per year, as each biker charity event I go to, I wind up spending lots of money at, all for good cause.
Typical charity event donations: $20 to get in, $40 for raffle tickets, $10 for food/drink, etc. I can shell out anywhere from $20 to $120 at a fun event, and all proceeds over cost of the events go directly to the organization/individual that benefits.
