While you’re at it, pick up a sheet cake on sunday from a local bakery. Have them write “Happy Birthday President Washington” on it. Then get disposable plates and forks and take it somewhere with a lot of foot traffic, where you can give cake away to all comers until it’s gone.
If you have an SAR or DAR in the area ask them to help.
I’d be really cautious about giving out food to the public at large.... that’s my legal background always rearing its ugly head.
