Leaking trans line on Jeep

Now it is my turn to ask a dumb question. I have an old Jeep Cherokee 1989 that I use only to plow the snow on my driveway. It is no longer registered and inspected, so I don't plan on ever driving it on the road again. I started it for the first time this year (yes, it started right away - yeah!). But I see that it now has a slight leak from one or both of the metal lines between the transmission and the radiator. After running for about ten minutes, it left a small puddle of trans fluid about 3" in diameter on the ground. I see that the leak is in the metal line directly under the engine oil pan. Now for the questions: do I just ignore it and add fluid every time I use it; do I cut the metal line and use a rubber hose to bridge the corroded section; or do I buy replacement lines and just replace them now? Right now, I am thinking of just ignoring it since it got cold out today and I don't feel like crawling around on cold ground again to fix it.
