I'm a weekend tuggie at a small UK club, being a tuggie has two extremes - boredom because no one wants a tow (although I'll fly a glider if no one wants a tow) or intense flying having to have eyes on stalks to spot gliders as you're returning to the airfield.
Tugging has been described to me (by someone with 20K+ tows) as the most dangerous job in flying due to all the aforementioned things that can go wrong.
There's also an emphasis on economical flying to maximise fuel and airframe/engine time.
Rewarding though when you have reasonable day and the Pawnee's fun to fly (in an agricultural way).
