In my opinion I think before you try to climb Mount Hood that you should go to Mount Rainier & climb to Camp Muir (10,080ft). This would be a good training place before you venture to Mount Hood. This would also give you and idea what its like to climb to at least 10,080ft even though Mount Hood is 11,239ft. You can find a partner on this site or on summitpost.com site. I wouldn't even mind if you tag along this summer with me to Camp Muir.
Then when you feel that your ready to climb Mount Hood you should find a partner who is experince in climbing or to find a guide that can safely take you up and back down again.
