"Pool disguised as pond with in ground trampoline in place of a diving board! yes, please. This is my idea of an in ground pool." -- I don't like the disguised as a pond idea but I LOVE the trampoline idea!
Thin posts (tiki torches) along walkway with round lights or chinese lantern style stringers between. Up high enough to stop cats/dogs playing with them or people tripping over them, cemented into ground with rocks if you have a problem with things being dug up.
