forestbiker,

I rode everywhere and all the time when I was a kid in Detroit. Then I gave up my bike for about 15 years. After doing a lot of traveling and settling down in north east PA, I finally got a new bike. The first time I went out I stuggled to go 2.5 miles and couldn't figure out why it was so hard. Then I turned around and coasted home. Detroit was completely flat. I had no idea what hills were like.
Just keep on riding and having fun.
