Why couldn't I towbar my fish to cruises or drags?

I appreciate all the input and realize that stuff can happen. I see an awful lot of people doing it and if I keep the speed reasonable (It's 55 mph here in glorious Kalifornia for towing anyway) I should be alright. With 4:56 gears to drive 75 miles one way is a little tough, not impossible but I am not 22 yrs old anymore (53).
