I agree with the other posters, it is not hard to climb over a normal fence, just look for a supportive brace post or corner (or gate, DUH). Cutting farmers fences makes you very unwelcome, especially if you let his livestock out.

I carry bolt cutters in my work truck now. Once I was racing to meet a helicopter to Heli-attack into a forest fire and the road was blocked by a gate, I used a pulaski to take down the gate but it was not a very clean job on the gate or on the tool.

If I am cutting a chain with a padlock on it I usually cut a link of the chain and replace it with a spare series lock from my truck, that way I may not need to cut the chain again the next time. This also allows me to secure the barrier again after I have gone through.
