Frank sent us an email: "We have a smallish yard but would like to install some sort of mini-playground for our three-year-old daughter. Do you have suggestions for a space about 12" x 12"?" That's a good question, Frank! While most of us would love to have a gigantic playground for our kids, space is often a factor in what we can realistically install -- even more so if you have patio furniture and a garden. We found Royal Palace Space Saver to be a nice higher-end set, while Little Tykes' Endless Adventures Adjustable Mountain Climber set is fun and only $259. If you have a tree, a old-fashioned tire swing is also a nice option. What can you recommend to Frank, savvy readers?
