I am a single grandmother and need some input. I live in a townhouse and have a small backyard. I live in So. Cal where it is usually over 100 degrees most of the summer but only occasionally freezes in the winter. I currently have a wood deck that is about 15 yrs. old and needs to be replaced. Because I walk with a cane, I am no longer able to do the maintenance on the deck and was considering a composite material but have no idea what are good ones. Where do I start and what do you recommend? Please help! Thanks, Nancy
