Deadline #8 HW #5 Grammar Assignment

After reading through my WP #1 and WP #2, I saw reoccurring grammar mistakes. The mistakes I was having was with commas and a few misspelled words. I believe I revise my papers thoroughly, and usually miss the small problems. I decided to go back to the Purdue Owl website to read over the comma web page (http://owl.english.purdue.edu/owl/resource/607/01/).
Here is a paragraph that I revised from WP #1 that had comma errors:

I have numerous personal experiences that support hunting in the debate. On one of my hunting trips in Arizona, my father and I confronted few animal-rights activists. We were hunting near Bartlett Lake for javelina, when activists appeared with pots and pans. They began shouting and banging pots and pans trying to scare the wildlife away so we could not hunt them. In addition, they were trying to make us leave the area. This was frustrating because my father and I spent countless days trying to find javelina, only to be run off the mountain. My father and I were there to help manage the javelina population around that area and to enjoy some father-and-son bonding. It was the irrational, misunderstood actions of activists that ruined our hunt. Another experience that I had was this past fall, when I was volunteering for the Montana Fish, Wildlife & Parks. I was working on hunter check stations, where we checked deer and elk harvested by hunters for valuable information on harvest statistics.

What I've learned is to watch out for the little mistakes, such as commas. From the paragraph above, I learned to not use commas in certain sentences where there is no transition. I was adding commas where I did not need them. After revising the paragraph and looking at the Purdue Owl site, I am focused to watch for comma errors and know when and when not to use one.
