+1 trillion.

I love riding, but my limitations really get in the way. I tried commuting 15 miles after work a couple times a week and it's not working out. I work full-time as a landscaper/groundskeeper and I already have arthritis problems with my hands and knees. My job tends to aggravate these conditions and after a day at work the last thing I want to do is hop on a bike and ride home. My knees especially hated carrying extra weight on the bike and combined with the hills I have to climb to get home I was miserable and I ended up straining my knees so I'm off the bike for a while.

My riding is pretty much limited to flat terrain and I have 1 flat route at my disposal. I only have 2 days off from work and I don't always want to ride both days. So if I have the energy for it, after work I'll drive to the flat bike path 2 miles away and ride even if it is only 30 mins. Normally I ride to the path, but dealing with the rush hour traffic isn't my idea of a relaxing/stress release type ride after work. Saturdays are the only day I have to drive to work and there are mountain bike trails a few minutes away so I'll sometimes pack up the mountain bike and if I'm up for it I'll cruise along on the easy trails.

Yes, I'd love to make cycling more of a lifestyle...using it for grocery runs, errands, commuting, but the reality for me is that my knees can't handle carrying much weight and/or climbing and aside from one bike path, there are hills everywhere I go. The good thing is I have an excellent public transportation system at my disposal and I have a bunch of grocery stores/markets within 10-20 minutes walking distance so I don't have too drive to much.
