My sister's B/F gave me a 70lb. bow!!!

I visited my sister in DE today, and after going cosmic bowling, we stayed at her house for a bit. Her bf Mike was showing me some of his hunting gear, cause I said I wanted to go with him this year...never been hunting before, and love deer and rabbit. After laughing at me tryin to pull back his crossbow, he hands me a 50-70lb compund, and says, try this. After strugglin a bit, he says "You want it? It's yours." and then hands me some arrows and tips to take home and practice with.Super Kewl! Deer season is comin up too.....
