start with your nearest Apartment Complex,
get a group from church and brainstorm (thunder and lighting and lots of air)
see the manager of the complex and ask if your group could help all the single mom's, it would be a great witness to the complex manager that all these Christians want to get out of their church and be a blessing...
find out what these single parents need and buy them the food, clothing etc... and of course give them a Bible...
is that a good idea?
