Almost all my pictures are taken by random people that I have asked if they would mind taking a picture of me. I usually give them a reason such as "My brother had a car like this" or "My kids used to play here in the park". Everyone has been very helpful and will take a couple shots. I carry a Canon PowerShot A2500 in an outside pocket of my purse. I've never had anyone go with me on my outings. I have even been taking a photo in a mirror at the shoe store and had a clerk come up and offer to take a picture for me.
