If he was familiar with her routes he would never have staged her bike where he did. The daughters boyfriend told LE all about where he looked and why. He told them where she tended to ride her bike and what she would wear. Her lover JL even said he looked up the routes she was going to ride on google. Everyone but Barry took an interest in where she was riding her bike.I don't see BM introducing her to mt biking either. I don't recall reading anything about that aspect, except that I simply don't see it. He still might have been familiar with her route or routes though. If she did solo rides then it is always wise to let someone know where you will be riding. It's not like road biking where a motorist might offer assistance. If out on a solo ride she might have told him in the past.
I've often wondered if she had some regular riding partners and, if so, what info did they give to LE that might have shed light on the alleged bike ride. Of course, this was in the midst of the Covid crisis when some my fellow cyclist chose to ride solo instead of the usual groups.
It's my opinion that Barry could care less about her hobby. He didn't like her having something she enjoyed. His comments made it clear he had no clue.
