I've decided to build something to train/have fun on at home, either indoors or maybe in the garden. im looking for ideas features people think would be a good idea I.e would including a crack be worth it ? Also my wife says it has to be for the kids too so is it worth having an anchor to tope rope them or am I better just spotting them. Being a builder the construction isn't a problem but I don't want to miss including anything that could be fun, so it's over to your creative selves
