Task: Question Answering
Input (English): Context: I drove it down to the Churchill boat ramp , and backed it down the treacherous soft - sand approaches . At about the high tide line , the substrate changes from fairly hard - packed coarse sand to a softer mix of finer sand , mud , and large rocks . Thinking I did n't want to get stuck in the soft stuff , I parked the truck at the high tide line . We deployed the lovely , lovely rollers I 'd bought ( link ) - they worked perfectly - and moved the Zodiac of Adventure , sans engine , up onto the back of the truck . 
Question: What is the narrator trying to participate in ?
Output (English): They are trying to participate in boating .
