simple, over the last 60 years I've probably spent no more than $6-7000 on gear, that's about $100 a year, and gets me as many as 25-30 paddling opportunities yearly for the price of a 7 day rental.
AND it's my gear- I know every quirk or issue with it, never have to settle for that last tent on the shelf or last boat on the rack, and there's no worry about damaging something that isn't mine...
