years ago I had a similar experience with 5 goats my mom had on he farm , and my mom would not pen them up . I had a 1974 dodge adventure sport that was my 1st ride and I washed it every day , but theses effen goats would clime up on the roof and **** everywhere ... I tried everything to keep them off .... so one spring day I filled a red 5 gallon plastic pail with water and put a lid on it , set it on top of the truck, sprinkled some oats on the lid and sat back and waited..... sure enough here come all 5 stupid goats , they climbed up and started nibbling on the top of the pail , so I took carefull aim with my dads 30-06 ..... BOOOOOOOM .... no more MOFO goats onna MOFO truck it was funny , goats, water an red plastic flying everywhere ...... so ya try this but with a smaller rifle .............. PS ..... no goats where harmed during this science project, my dad patted me on the shoulder and said , hell I would of never thought of that .... my mom call me a little bastard
