There are the ramps I have....
www.canadiantire.ca
The only problem for me is that I'm only 5'7 and I'm not comfortable / stable enough to push them up myself.
GTAM has provided me some tips on getting the bike up, but it was over winter so I didn't try them out.
I'd like a stable and solid platform, so can just make life easier / safer. I had the bike fall off on me once when I was putting it onto the Trailer-In-A-Bag and while I was able to lift it up again solo...I don't want to go through that again.
I think an 8ft 2x10 or 2x12 will make a nice ramp for my needs. Would probably need to reinforce it with a 2x4 underneath for rigidity purposes...but it would be more stable than what I have now.
EDIT: Saw this at PA yesterday....snazzy. Pricy.
