I worked at an airfield in the states and payed for an entire instrument rating one summer. I mowed grass, watered flowers, painted hangers, all the pee- on jobs and it was well worth it. Meet many great people who let me fly their airplanes and made some great connections and career adivce. This was just a mom and pop airfield so there wasn't much attitude, just friendly folks mostly. Wouldn't have traded that experience for the world. It payed horrible but hey you have to be in it to win it.
