Go Ray! What a beautiful bike trail!!!
If I was you, I might re-think riding roads and stick to trails. As RNI saw an active 72 yo gentleman, hard core cyclist- with all the gear and whatnot- completely sidelined by a compound fracture from bike accident going downhill down a curve, slipped in the sand, and IIRC, there were some parked cars. Think how hard it would be to go from your present mobility level to severely limited in an instant.
At my age, I've decided a bit of caution is warranted. My own personal wake up call: I love to boogie board in the ocean. One time in California surf a few years ago, I attempted a large wave and was thrown headfirst into the sand and felt a jolt from my head down my spine. Very scary! For a split second I thought I had broken my neck and paralyzed myself. That can happen in shorebreak surf. Ever since, I am very respectful of the waves. If they are large, powerful, and or shorebreak, I defer and wait for a smaller gentler wave. Not worth the risk.
Mobility Rocks! That's why we got these hips replaced, right?
So we can keep right on going as long as possible!
