My city has a nice grade separated trail system that is dead quiet at night with the exception of the occasional homeless person or the time I flew around a bend to find kids setting off fireworks in the middle if the path (extreme fire danger that year too >:-( )
I have to cross a fee stroads to get from the trail back home and my destination isn't always perfectly trail adjacent, but on nice summer nights I like to ride the 25 miles into the entertainment district and back 90% of which is trail riding.
Nice resource. I get good exercise and eat a lot of raw or unprocessed foods, but my portions are whack and there's not a lot of consistency day to day. I've been wanting to clean up my diet for a while and I'm gonna add this to my planning document.
