Do I Want To Be A Foster Parent?

I'm guessing that my over enthusiasm with my little puppy caught their attention, but today at the dog park I was approached by members of the local Siberian Husky Rescue/Adoption organization. They asked if I might be interested in becoming a foster parent to rescued Labs.
I explained that I didn't know anything about fostering or what exactly a rescue/adoption organization even did. Apparently because Siberian Huskys are a very popular breed there are often times that they require foster homes to place displaced dogs.
The mission of a dog rescue organization is to find foster placements, and ultimately adoption homes for dogs that may have been lost, abandoned, or abused.
I explained that I didn't have the physical resources of time and energy to take on the responsibility and commitment of another dog at the present time. I do think, however, that I will look into donating other resources to assist their cause it seems like a good thing to me.
