need ideas

hi everyone, my horse got an eye infecion last week and spent a week in the hospital. we do not have a barn built yet(this summer lol)so i had to find a stall close by. i asked my neighbors that own a horse farm they said sure the whole barn is empty. gave me two stalls one for kaazmo and one for feed and hay. then said as long as i clean up my own stall and feed i can have it for free. COOL BEANS!! so now i would like to get them a special gift but my mind is a blank (what else is new lol) they breed and race horses small time business but very serious about it. they do have a nice old house but not much on landscaping other than grass and trees they are always on the go. that's all i know about them. so any ideas would be great.
