Joe raised the question in a different thread, so I thought I would make it a topic and go first.
Between club fees, clinics, entry fees, travel and gear; I would estimate I spend around $7k a year for wrestling. I would guess that tournaments attended are the biggest variable in dollars spent as they bring the additional costs of hotels, fuel, childcare, meals, etc. We have never attended some of the major tournaments that are more than 6-8 hours away and we don't spend much on shoes, but I will admit we will spend the extra $15-30/night for a hotel room after a few rough nights trying to save a dollar!
