Hi guys,
First post here at on BF. Nice to see others hitting up the sand for riding. I live in San Diego, specifically Pacific Beach and when the tide is medium to low it is so easy to ride on the sand near the water line since it is usually very packed down and have had success with ebery thing from my 29er to standard 26" beach cruisers and all the way down to my cyclocross bike w 32mm width cross tires. Its a great way to beat all the boarwalk bike path crush in Summer here.
Cheers n happy cruising
