Okay. Before buying any courses, I'm gathering equipment. So I decided I would use a ladder as my stall bar, by buying an extension ladder and hooking it to a pole in the park via tie down straps, as explained here: https://www.gymnasticbodies.com/forum/topic/11662-ladder-as-stall-bars-substitute/. Speaking of which, is that safe? Anyways, I was thinking of buying either this: http://www.homedepot.com/p/Werner-8-ft-Aluminum-D-Rung-Straight-Extension-Ladder-with-300-lb-Load-Capacity-Type-IA-Duty-Rating-D1508-1/203134220?cm_mmc=shopping-_-googleads-_-pla-_-203134220&ci_sku=203134220&ci_gpa=pla&ci_src=17588969&gclid=Cj0KEQjw7IWgBRCjv8Cv4vfC3ckBEiQAE7nvR9AFTBrg7PqJtNMXkWPa3MQJXWtDCDjaXw8ENhu-vKAaAmQe8P8HAQ which is an 8 foot, aluminum ladder. OR http://www.homedepot.com/p/Xtend-Climb-8-5-ft-Telescoping-Aluminum-Extension-Ladder-with-225-lb-Load-Capacity-Type-II-Duty-rating-750P: which is a telescoping ladder. Do you think the telescoping ladder is any less stable? The only reason I was looking at the telescoping one, is because it's more portable, and I don't want to walk up the hill with an 8 foot ladder! So, does anyone think the first one is better. Is this idea even safe? Thanks Sorry for the long post.
